Our Top 7 Best Upgrades For 6.7 Powerstroke Reviews – Expert Tested & Recommended
1. S&S Diesel CP4 to DCR Pump Conversion Kit for 2011 and Newer Ford 6.7L Powerstroke
🌟 Key Features That Stand Out
- ✓ DCR Pump Technology: Replaces the failure-prone CP4 with a more durable two-piston design.
- ✓ No Tuning Required: This is a true plug-and-play kit that works with factory emissions and software.
- ✓ Enhanced Lubrication: Features a pressure-lubricated cam and bushings for extreme longevity.
- ✓ High Displacement: Offers a 25% increase in displacement compared to the stock pump.
- ✓ Fuel Compatibility: Fully compatible with biofuel and modern low-lubricity diesel fuels.
💡 Why We Recommend It
The S&S Diesel DCR Conversion Kit is widely considered the ultimate reliability upgrade for the 6.7 Powerstroke. The factory CP4 high-pressure fuel pump is known for catastrophic failures that can send metal shards throughout the entire fuel system, costing upwards of $10,000 in repairs. This kit replaces that “hand grenade” with a robust Stanadyne-based DCR pump that is built to last.
What makes this kit particularly impressive is its ease of installation. It maintains an OE fit and function, meaning you don’t have to worry about aftermarket tuning or “deleting” components to make it work. For anyone who uses their truck for serious work or long-distance towing, this provides the peace of mind that a fuel pump failure won’t leave you stranded.
🎯 Best For
This product is ideal for: high-mileage drivers and heavy towers who want to eliminate the #1 failure point on the 6.7 engine.
⚖️ Pros and Cons
✅ Pros

— Verified Buyer
2. H&S Motorsports Upper Fuel Filter Conversion Kit for 2011-2025 Ford 6.7L Powerstroke Diesel Trucks
🌟 Key Features That Stand Out
- ✓ Billet Aluminum Housing: Replaces the weak factory plastic cap with a rugged metal housing.
- ✓ Prevents Fuel Leaks: Eliminates the cracking issues common with original plastic components.
- ✓ Easier Serviceability: You don’t need to remove factory fuel line fittings during every filter change.
- ✓ Made in the USA: High-quality construction and materials sourced domestically.
- ✓ Complete Kit: Includes all necessary lines and fittings for a clean installation.
💡 Why We Recommend It
The H&S Motorsports Upper Fuel Filter Conversion Kit is a must-have for owners who are tired of dealing with brittle plastic parts. On the 6.7 Powerstroke, the factory fuel filter housing is plastic, which can crack over time due to heat and pressure. When this happens, it leads to fuel leaks that can be both messy and dangerous.
This kit simplifies your maintenance routine. By converting to a spin-on style filter and using a billet housing, you reduce the risk of stripping threads or breaking plastic tabs. It’s a one-time install that makes every future fuel filter change faster and safer for your engine.
🎯 Best For
This product is ideal for: DIY mechanics who want to make their fuel filter changes easier and more reliable.
⚖️ Pros and Cons
✅ Pros
- Rugged billet aluminum construction
- Protects against engine bay fires from leaks
- Simplifies the filter change process
- High-quality fittings included
❌ Cons
- Higher cost than just replacing the plastic cap
- Initial install takes some time
💬 What Customers Say
“The factory plastic cap cracked on me while I was on a road trip. Wish I bought this sooner. It’s a solid piece of hardware and fits perfectly.”
— Verified Buyer
“Much better than the OEM setup. It looks great under the hood and I don’t have to worry about fuel spraying everywhere if the plastic gets old.”
— Verified Buyer
3. Aluminum Fuel Filter Conversion Kit for 2011-2024 Ford 6.7L Powerstroke F250 and F350 Super Duty
🌟 Key Features That Stand Out
- ✓ High-Flow Design: Converts the stock system to use high-flow BF7967 filters for better performance.
- ✓ Built-in Sensor Port: Includes an additional 1/8 ORB port for adding fuel pressure sensors easily.
- ✓ Upgraded Fittings: Replaces plastic return fittings with high-quality aluminum alloy versions.
- ✓ Cost-Effective Maintenance: Standard spin-on filters are generally cheaper than the OEM Ford plastic assemblies.
- ✓ Durable Materials: Combination of aluminum alloy and steel ensures high resistance to corrosion.
💡 Why We Recommend It
This conversion kit is the perfect balance between price and performance. It allows you to ditch the expensive and fragile OEM plastic fuel filter setup in favor of a heavy-duty aluminum housing that accepts a standard, high-flow filter. This is especially beneficial for trucks that are running higher horsepower or those that just want to save money on maintenance over time.
What really sets this “Best Value” pick apart is the inclusion of the 1/8 ORB port. If you want to monitor your fuel pressure (which we highly recommend for the 6.7), this kit makes it incredibly easy to add a sensor without hacking into your factory lines. It’s a well-engineered solution that addresses multiple factory flaws at a fraction of the price of some competitors.
🎯 Best For
This product is ideal for: budget-conscious owners who still want a massive upgrade in durability and the option to add sensors.
⚖️ Pros and Cons
✅ Pros
- Very affordable compared to name brands
- Enables easy fuel pressure monitoring
- Improves fuel flow to injectors
- Compatible with a wide range of model years
❌ Cons
- Finish isn’t as polished as premium kits
- Instructions can be a bit sparse
💬 What Customers Say

— Verified Buyer
“Everything fit exactly as it should. Replaced the old plastic bits that were starting to look questionable. Highly recommend for the price.”
— Verified Buyer
4. H&S Motorsports Intercooler Pipe Upgrade Kit for 2017-2024 Ford 6.7L Powerstroke F250 and F350
🌟 Key Features That Stand Out
- ✓ 5-Layer Silicone Boot: Features a steel-reinforced core that won’t burst under high boost.
- ✓ Billet Coupler: Patented design ensures a leak-proof seal that lasts the life of the truck.
- ✓ Fluorocarbon Liner: Special coating makes the tube impenetrable to oil, preventing “soaked” boots.
- ✓ Rated for 100+ PSI: Far exceeds factory boost levels for maximum safety.
- ✓ Simple Installation: Bolts on in minutes with basic hand tools and no tuning required.
💡 Why We Recommend It
If you own a 2017+ Powerstroke, you may have heard stories of the factory cold-side intercooler pipe “popping” or cracking. Because the stock pipe is plastic, it becomes brittle over time and often fails under heavy towing loads. This H&S upgrade replaces that weak link with a heavy-duty silicone and billet aluminum assembly.
This is one of the easiest 6.7 Powerstroke performance upgrades to install yourself. It doesn’t just add reliability; it also improves engine appearance and ensures you don’t lose boost pressure. It’s an essential upgrade for anyone who wants to avoid being stranded on the side of the road with a blown intercooler pipe.
🎯 Best For
This product is ideal for: owners of 2017 and newer trucks who want to prevent a common roadside breakdown.
⚖️ Pros and Cons
✅ Pros
- Massive improvement over plastic OEM
- Oil-resistant liner prevents degradation
- Quick 20-30 minute installation
- Supports extreme boost levels
❌ Cons
- Higher price point for a single pipe
- Requires reusing some factory clamps
💬 What Customers Say
“This should be a standard upgrade for any 6.7 owner. It took me 20 minutes to install and looks much better than the plastic one that was about to pop.”
— Verified Buyer
“I’ve hit 40 PSI of boost towing my trailer up hills and this pipe doesn’t even flinch. Well worth the money for the reliability.”
— Verified Buyer
5. Replacement Crankcase Air Oil Separator Assembly for 2011-2024 Ford 6.7L Powerstroke Super Duty Trucks
🌟 Key Features That Stand Out
- ✓ Sludge Prevention: Separates oil from crankcase gases to keep your intake and valves cleaner.
- ✓ Engine Health: Protects seals and gaskets from excessive pressure buildup.
- ✓ Direct Fit: Designed to match the factory dimensions for a hassle-free swap.
- ✓ Heat Resistant: Made from premium materials that won’t warp under high engine bay temperatures.
- ✓ Broad Compatibility: Fits all Super Duty 6.7L Powerstroke models from 2011 to 2024.
💡 Why We Recommend It
The crankcase air oil separator is an often-overlooked component that plays a huge role in your truck’s long-term health. Over time, the factory separator can clog, leading to increased oil consumption and oil mist entering your turbocharger and intake. This “Replacement Assembly” is an excellent way to maintain proper ventilation without spending a fortune.
What we appreciate about this specific model is that it simplifies the transition for older trucks. While 2017+ models don’t use a sensor on this part, 2011-2016 models do. This unit allows you to clear any codes and maintain performance efficiently. It’s a smart preventative maintenance item that protects your turbo and keeps your engine running “cleaner.”
🎯 Best For
This product is ideal for: owners looking to reduce oil consumption and intake sludge as part of a high-mileage maintenance plan.
⚖️ Pros and Cons
✅ Pros
- Excellent value for a full assembly
- Helps prevent turbocharger oiling issues
- Perfect fit for Super Duty trucks
- Improves overall engine longevity
❌ Cons
- Does not include a built-in sensor
- May require a code reset on early trucks
💬 What Customers Say

— Verified Buyer
“Exact fit for my 2018 F-250. Very easy to swap out and the build quality seems as good as the Motorcraft part.”
— Verified Buyer
6. Sinister Diesel Fuel Filter Conversion Kit for 2011-2024 Ford 6.7L Powerstroke Diesel Reliability Upgrade
🌟 Key Features That Stand Out
- ✓ Billet Aluminum Build: CNC-machined for incredible strength and a perfect seal.
- ✓ Signature Blue Finish: Anodized for corrosion resistance and a premium engine bay look.
- ✓ Safe Fuel Delivery: Protects injectors by ensuring reliable, clean fuel delivery.
- ✓ Leak Elimination: Specifically designed to remove the fragile plastic housing that sprays fuel when it cracks.
- ✓ Direct Bolt-On: No modifications required to your Super Duty for installation.
💡 Why We Recommend It
Sinister Diesel is a household name in the Powerstroke world, and this kit shows why. It’s not just a reliability fix; it’s a statement piece for your engine bay. By replacing the OEM plastic upper filter setup, you eliminate the risk of a fire or engine damage caused by cracked housings spraying diesel onto a hot engine.
We love this kit for daily drivers because it adds a level of “set it and forget it” durability. The CNC-machined aluminum is much more resilient to the constant vibrations and heat cycles of a diesel engine. Plus, if you’re a fan of the classic Sinister blue, it really ties the whole engine bay together while adding professional-grade protection.
🎯 Best For
This product is ideal for: truck enthusiasts who want high-performance looks combined with bulletproof fuel system reliability.
⚖️ Pros and Cons
✅ Pros
- Top-tier manufacturing quality
- Anodized finish lasts for years
- Greatly reduces engine bay fire risk
- Solid, heavy-duty feel
❌ Cons
💬 What Customers Say

“Expensive but worth it. The stock plastic housing is a joke compared to this. Plus, it looks amazing when I pop the hood.”
— Verified Buyer

🌟 Key Features That Stand Out
- ✓ Upgraded Aluminum Alloy: Offers high hardness and wear resistance compared to stock plastic.
- ✓ Double Layer Sealing: Uses a double-layer NBR design to ensure no fuel leaks occur.
- ✓ Manganese Steel Clamp: Includes a heavy-duty clamp that is corrosion-resistant and won’t loosen.
- ✓ Anodized Surface: Provides an extra layer of protection against the elements and fuel chemicals.
- ✓ Direct Replacement: Designed to swap perfectly with factory part number HC3Z-9A564-A.
💡 Why We Recommend It
Sometimes the smallest upgrades are the most important. This return line connector addresses a common annoyance for 2017-2020 owners: the plastic connector that can snap during a filter change or simply crack from heat. Once that plastic breaks, your truck is dead in the water until you get a new line.
This aluminum version is essentially “insurance” for your fuel system. It’s inexpensive, easy to install, and significantly stronger than the piece it replaces. If you’re already under the hood doing a fuel filter change, swapping this out is a no-brainer to ensure you never have to deal with a broken plastic return fitting in the middle of a job.
🎯 Best For
This product is ideal for: mechanics and owners who want to eliminate “nuisance” failures and brittle parts during routine maintenance.
⚖️ Pros and Cons
✅ Pros
- Very low cost for high peace of mind
- Superior double-sealing design
- Resistant to cracking and impact
- Simple “while you’re in there” upgrade
❌ Cons
- Only fits specific 2017-2020 range
- Requires careful handling of the small clamp
💬 What Customers Say
“Don’t risk the plastic one breaking. This was super cheap insurance for a common leak point and took only a minute to put on.”
— Verified Buyer
“The quality of the aluminum is great. It’s much tighter and more secure than the stock clip. Every 6.7 owner needs this.”
— Verified Buyer
Complete Buying Guide for Best Upgrades For 6.7 Powerstroke
Essential Factors We Consider
When looking for the best upgrades for 6.7 Powerstroke, we focus primarily on reliability over raw horsepower. The 6.7 is already a powerful engine, but its long-term survival depends on addressing weak points like the CP4 injection pump, plastic intercooler pipes, and plastic fuel filter housings. We look for billet aluminum components and reinforced silicone because these materials can withstand the high heat and pressure cycles inherent in a diesel engine.
Budget Planning
Upgrading a Powerstroke can range from $20 for a return line connector to over $2,000 for a fuel pump conversion. We recommend prioritizing “preventative” upgrades first. If you have a limited budget, start with the intercooler pipe and fuel filter conversion kits. These address immediate failure points that can leave you stranded. The CP4 pump conversion is the most expensive but should be the ultimate goal for any owner planning to keep their truck for the long haul.
Final Thoughts
The Ford 6.7L Powerstroke is a workhorse, but it isn’t perfect from the factory. By selectively choosing reliability upgrades, you aren’t just making the truck faster or better-looking—you are making it more dependable. Investing in these parts now can save you thousands in emergency repairs later, keeping your Super Duty on the road and out of the shop.
Frequently Asked Questions
Q: Why should I replace the CP4 pump on my 6.7 Powerstroke?
A: The CP4 pump is known for catastrophic failure, especially when used with American diesel fuel which has lower lubricity. When it fails, it can send metal debris through the entire fuel system, requiring a complete and very expensive overhaul.
Q: Will these upgrades void my Ford warranty?
A: Many of these upgrades, like the intercooler pipe or fuel filter kits, are simple bolt-ons. However, significant changes like a pump conversion could potentially affect your warranty coverage. Always check with your dealer or look for kits that maintain OE fit and function.
Q: Do I need a “tune” to install these upgrades?
A: Most of the products on our list, including the S&S DCR pump conversion and all filter kits, are specifically designed to work with factory software and do NOT require a tune.
Q: Is it difficult to install an intercooler pipe upgrade?
A: No, this is one of the easiest DIY upgrades. It usually requires only a few basic hand tools and about 30 minutes of your time.
