Best Upgrades for Your Ford 6.7 Powerstroke Diesel

The Ford 6.7L Powerstroke diesel engine has long been known for its powerful towing capacity, high torque output, and long-term durability. Introduced in 2011 and refined in subsequent years, this powerhouse has evolved into one of the most reliable diesel engines on the market. But like any vehicle, the 6.7 Powerstroke can benefit significantly from aftermarket upgrades—enhancing everything from horsepower and throttle response to fuel economy and engine longevity.

Whether you use your Ford Super Duty for towing, hauling, work, or play, the following upgrades can help you get the most out of your 6.7 Powerstroke diesel.

1. Cold Air Intake Systems

Why upgrade?
Stock air intake systems can be restrictive. A cold air intake brings in cooler, denser air, allowing your engine to breathe better and burn fuel more efficiently.

Benefits:

  • Increased horsepower and torque

  • Improved throttle response

  • Enhanced fuel economy

  • Better turbo efficiency

Top Brands:

  • S&B Filters

  • AFE Power

  • Banks Power

2. Performance Tuners & Programmers

Why upgrade?
A tuner or programmer unlocks the hidden potential of your Powerstroke by adjusting fuel maps, turbo boost, and shift points for optimal performance.

Benefits:

  • Up to 150+ horsepower gains

  • Increased torque

  • Improved towing performance

  • Custom tuning for different driving needs

Top Tuners:

  • SCT X4

  • Edge Evolution CTS3

  • Bully Dog BDX

Note: Custom tuning is recommended for heavily modified engines.

3. Exhaust System Upgrades

Why upgrade?
The stock exhaust is designed for emissions control and noise reduction—not performance. Upgrading to a high-flow exhaust reduces backpressure and improves turbo spool-up.

Benefits:

  • Cooler exhaust gas temperatures (EGTs)

  • Increased fuel economy

  • Better turbo efficiency

  • More aggressive sound

Popular Options:

  • 4” or 5” turbo-back exhaust kits

  • DPF-back exhaust systems for emissions compliance

4. Blue Spring Fuel Pressure Upgrade Kit

Why upgrade?
This simple yet effective upgrade increases blue spring fuel pressure kit to the injectors, improving performance and protecting injectors from damage.

Benefits:

  • Extends injector life

  • More consistent fuel pressure

  • Smoother idle and acceleration

  • Simple and affordable upgrade

Recommended for:
2011–2016 Powerstroke models

5. Intercooler and Piping Kits

Why upgrade?
The stock intercooler system can struggle under high boost. Upgraded intercoolers and charge pipes improve airflow and reduce heat soak.

Benefits:

  • Lower EGTs

  • Increased durability under boost

  • Better towing performance

  • More stable engine temperatures

Top Brands:

  • Mishimoto

  • Banks Power

  • No Limit Fabrication

6. Head Stud Kits (ARP Studs)

Why upgrade?
If you plan to push serious power or tow heavy loads regularly, upgrading from factory head bolts to head stud kit  ensures head gasket integrity.

Benefits:

  • Prevents head gasket failure

  • Greater clamping force

  • Essential for tuned or deleted trucks

  • Increased engine reliability under stress

7. Upgraded Turbochargers

Why upgrade?
Stock turbos are adequate, but an aftermarket turbo upgrade can significantly improve airflow and reduce turbo lag.

Benefits:

  • Massive power increases

  • Better boost response

  • Cooler EGTs

  • Improved towing and performance

Top Picks:

  • Garrett PowerMax

  • KC Turbos

  • BD Diesel Performance

8. Transmission Tuning and Upgrades

Why upgrade?
The 6R140 automatic transmission is tough—but adding power without addressing transmission tuning can shorten its lifespan.

Benefits:

  • Smoother, firmer shifts

  • Improved torque converter lockup

  • Reduced transmission temps

  • Better power delivery under load

Solutions Include:

  • Custom transmission tuning

  • Upgraded valve bodies and torque converters

Why upgrade?
Real-time engine data is essential for diesel performance builds. Digital monitors keep you informed and can help prevent damage.

Top Features:

  • EGT, boost, transmission temp monitoring

  • DTC code reading and clearing

  • Customizable alerts

Conclusion

Upgrading your Ford 6.7 Powerstroke diesel doesn’t just mean more horsepower—it means improved reliability, greater efficiency, and a better driving experience. Whether you’re a weekend warrior, a heavy-duty hauler, or just want to improve longevity and fuel economy, the upgrades listed above offer proven performance.
