Performance injectors add power and improve performance. The injectors in the 1994-1997 Powerstroke are very low flow from the factory. The smallest performance injectors make a large improvement in the OBS towing and driving in real world conditions. The best selling injectors for the 1994-1997 are the stage 1 and stage 1.5 injectors.

160cc vs 180cc:
The stock flow of the 1994-1997 injectors are 90cc. We recommend 160cc for most OBS trucks in stock form without turbo upgrades or an aftermarket intercoolers. If you have upgraded the air into the engine 180cc are a great option for more power
