An ideal performance upgrade for your OBS. They feature all new internals, are fully flow-tested to ensure optimal operation, and have an 18-month unlimited mileage warranty. And have the potential to increase horsepower within the range of 50-100 hp to the rear wheels with a custom tune.

Part Number: WDI stage1-160-stock

• Set of 8
  
• New tungston-coated plungers and barrels
• New Nozzles and o-rings
• Fully flow tested to match inflow within 1%
• 160cc flow rate is for less smoke and 20-25 hp less than the 180cc
• 18 month warranty 

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.
