WDI 175cc Conventional Injectors - 6.0 Power Stoke


This is our most popular injector. They flow 40cc’s of fuel over stock and best utilized with a brand new 30% nozzle. They unload fuel faster for more high end horsepower gains. These injectors are a great all around set. With these injectors you will have to run custom tuning to get them to idle properly and to maximize the potential of the injectors. These injectors will require aftermarket lift pump and regulated return to ensure the proper fuel is supplied to the injectors.

We remanufacture all internal mating surfaces, inspect all pieces of the injector, replace defective parts,and test each solenoid. Every o-ring in and on the injector is replaced. Every injector we remanufacture is flow tested on our in house flow bench. Each injector has 4 tests that it has to pass before being shipped out to you. 

Our brand new spool valves are superior to OEM because we use a higher quality steel made to our specific guidelines. They ensure a quiet smooth idle, great cold starts, and outstanding reliability.

These injectors are good for about 440-550 RWHP fuel. 175/75s and Garrett Powermax turbo with Wicked Wheel is a good setup and capable of 540RWHP with supporting mods and tow friendly. A smaller BorgWarner S300 SX-E turbo would be good match as well.

Injectors come with 1 year warranty starting when you receive injectors (not install).

Due to high volume of 6.0 injector orders these will not ship til about 2-3 weeks.
