Best Power Stroke Diesel Upgrades to Buy

A roundup of the highest-value upgrades for a Ford Power Stroke — tuners, intakes, exhaust, gauges, and reliability parts worth adding to the 7.3, 6.0, and 6.7.

By Powerstroke Parts Team Updated July 22, 2026

The best Power Stroke upgrades aren’t about chasing a dyno number — they’re about usable power, cooler temps, and reliability that lets you enjoy it. Here are the picks that deliver, with new parts on Amazon and used/OEM performance parts on eBay Motors.

1. A Quality Tuner

A tuner is usually the single biggest improvement in throttle response and usable power, and it adds live monitoring for towing. On modern trucks it transforms the driving experience. Start here.

2. Airflow: Intake and Exhaust

A freer air intake feeds the turbo cool, dense air; a diesel exhaust upgrade frees flow and drops exhaust gas temps. Together they help power and heat management, especially under load.

3. Gauges and Monitoring

You can’t manage what you can’t see. Gauges for boost, EGT, and transmission temp are essential once you tune or tow hard — they turn guesswork into data.

4. Reliability First

Before big power, secure the foundation: head studs on the 6.0/6.4 and an EGR and cooling refresh keep the engine sealed and cool. Power is only fun when the truck is dependable.

Frequently Asked Questions

What's the single best first upgrade for a Power Stroke?
For most owners, a quality tuner delivers the biggest, most noticeable improvement per dollar — more usable power, better throttle response, and often better towing manners. On a 6.0, secure the head gaskets with studs first if you plan to add much power.
Do bolt-ons actually help a diesel?
Yes — a freer intake and exhaust lower exhaust gas temps and let the turbo breathe, which helps both power and heat management when towing. The gains stack best alongside tuning.
