FAQ
Do I need an HX40 downpipe on 2003-2004 trucks?Yes. 2003-2004 applications require an HX40-style downpipe (PN HX40DP3). See our recommended parts above.
Is tuning required?Custom calibration is strongly recommended to take full advantage of the 66mm compressor and to manage boost/EGTs safely.
Will this work with stock injectors?It can operate with stock injectors, but peak results come with upgraded injectors and a built transmission.
