1994-1997 Powerstroke Stage 1.5 Injector Set w/ 30% Nozzles (WDI stage1.5-160-30)

Fits

Note: Custom Tuning is REQUIRED

If you're looking for a little extra pick-me-up in your 7.3, these are the injectors for you;  with the extra fuel of the stage 1.5 injectors, the increases can be up to 380hp total horsepower. VS. Stock AA injectors are limited by fuel delivery and even with performance tuning only about 235 hp total is the limit of the gains.

Part Number: WDI stage1.5-160-30

• Set of 8
• 30% Over nozzles
• Larger nozzles mean more fuel; more fuel means more heat and smoke
• Significant power gains
• 160cc injectors if you have a stock turbo and stock intercooler
• With the addition of the OBS 66mm turbo upgrade or intercooler, Warren suggests the 180cc option

• Intake/air upgrades are recommended with larger nozzles

180cc vs 160cc: 180cc is the best choice for most OBS trucks. The only time Warren recommends the 160cc injectors is in high altitude locations or for the customer who doesn't want a large power increase. 

The only benefit of the 160cc is that a completely stock OBS truck will see large gains without needed (recommended) exhaust or intake modifications. The stock injectors have an effective flow rate of 90cc.
