WDI 8mm Hybrid Injectors - 6.0 Power Stoke


These are competition injectors and the biggest 8mm hybrid that you can run on stock HPOP. 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 a large 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 capable of around 900RWHP with supporting mods. A BorgWarner 369SX-E, S400 SX-E or compounds turbo setup would be our recommendation.

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.
