The 6.7-liter Power Stroke, introduced for 2011, was the first Power Stroke designed and assembled by Ford itself rather than supplied by Navistar. Ford developed it with the Austrian engineering firm AVL. The block was cast by Tupy. It uses one sequential turbocharger with a dual-sided compressor wheel, plus a particulate filter and an SCR system for emissions. Rated output climbed from 390 hp and 735 lb-ft in 2011 to 475 hp and 1,050 lb-ft by 2020, with a high-output version rated at 500 hp and 1,200 lb-ft from 2023.
What made it successful
Ford's in-house control of the design allowed steady rating increases through several updates. It gave Ford the top output figures in the heavy-duty class at points during its run, according to its own ratings history.
Market position
It has been Ford's only diesel in F-250/F-350 pickups throughout this period, and its ratings rose repeatedly, reaching a 2023 high-output rating well above earlier versions. Ratings comparisons with Ram and GM by model year are not yet sourced.
Rebuild Potential
Tier BEditorial opinion.
The 6.7L Power Stroke has deep parts, community, and aftermarket support, and its problems are well documented. The CP4 pump risk is the biggest cost, and the emissions system adds complexity, which holds it at tier B. Later 2020-and-newer engines are generally reported as the strongest years.
Best year ranges
- 2020-2026: Secondary sources say the CP4 fuel pump concern and turbo design were improved from about 2020; this is not confirmed by a primary source.
Known weak points
The Bosch CP4.2 high-pressure fuel pump can fail catastrophically and contaminate the fuel system with metal debris on 2011-2020 engines.
Common fix: Replace the pump and the contaminated fuel system with OEM-spec parts, keep fuel filters current, and monitor fuel supply.
Turbo actuator wear and sticking VGT vanes cause underboost, especially on 2011-2012 engines.
Common fix: Service or replace the turbo actuator and clean the turbo.
The EGR cooler can crack, typically around 130,000-160,000 miles, and the particulate filter accumulates ash after about 150,000 miles.
Common fix: Replace the EGR cooler with a quality unit and service or replace the particulate filter with compliant parts.
Common upgrade categories
- OEM-spec fuel pump and filtration
- Turbo actuator and cooling service
- EGR cooler replacement
- Transmission and cooling upgrades
- Bolt-on intake and exhaust within local legal limits
This engine is emissions-equipped (EGR, particulate filter and, from 2011 on some engines, DEF/SCR). Keep the emissions equipment the truck was built with; repair or replace it with compliant parts. Removing or defeating it on a vehicle originally equipped with it is illegal under federal law. Rules vary by state (for example California/CARB), so check local law and model-year requirements before modifying.
