Which Tube To Install
The JLT Intake Comes with 2 intake tubes and 3 couplers.
NO TUNE Required Tube: This intake tube has 1 compatible coupler that will work with the stock throttle body and can be stretched over a a 95mm TB.
5" TUNE REQUIRED Tube: This intake requires a custom tune(rescaled MAF values). Two different couplers are included and compatible with this tube. The smaller of the two fits the OEM or 95mm TB. The larger of the two works with a 103mm TB.
