WDI 155cc Conventional Injectors - 6.0 Power Stoke


This is our smallest upgrade. We modify your injector to flow 20cc’s over stock. You will see a gain in fuel economy and low end torque. With these injectors you will have to run custom tuning to get them to idle properly and to maximize the potential of the injectors. Blue spring and upgraded banjo bolts are recommended.

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 430-470 RWHP and do work well with stock turbo or a little bigger than stock like a Garrett Powermax or BorgWarner 362/68 SX-E.

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 if we do not have in stock.
