Vehicle Fitment:
- 2008-2014 Chevrolet Silverado 1500 models with the 4,8L, 5.3L or 6.2L engine
- 2008-2014 Chevrolet Silverado HD Models with the 6.0L engine
Notes:
- This kits harness uses OEM connectors in tandem with OEM products. Fit and finish look 100% stock under your vehicle. Your truck will pick up 10-15rwhp on e78 or better depending on the tune.
- Note: While the GM flex fuel sensor can be installed and works perfectly fine to run pump gas with your vehicle without a tune, to run E85 your truck must have a tune to run E85 fuel. DO NOT INSTALL & RUN E85 WITHOUT A PROPER TUNE. Make sure your tuner has verified your sensor is hooked up and reading the ethanol content before adding e85 to your vehicle.
