We hope you are satisfied with the look and performance. You may use any polish or wax on the pipe as it’s painted with the same high quality paint as your car. It is also recommended to use some tire shine on the rubber elbow. Take your time and it will be a smooth install. Please review complete instructions prior to installing.
1 Verify you have all of the following parts included in the kit: (1) JLT Painted Pipe with IAC, PVC, and Vacuum line fittings, (1) 45 degree Rubber Elbow w/ clamps to connect throttle body to JLT Pipe, (1) Silicone Reducer w/ clamps to connect JLT pipe to MAF, (1) JLT heat shield, (1) Billet MAF Adaptor with bolts, (1) 4×12” S&B Air Filter, (1) 5/8” Hose, (1) 3/4” Hose, (1) Vacuum Line, (1) Silicone Spacer (for use on early Lightnings with 80mm MAF only)

3 Remove the factory Air Box Assembly from the Throttle Body to Air Box.
4 Remove the Mass Air Flow Sensor from the airbox and install the Billet MAF adaptor in the JLT kit.
5 Install the JLT heat shield onto the adaptor, rotating it in the direction you want to block engine heat.
Note: Keep the MAF in its stock rotation. Meaning, remember where the plug position was stock and return it to the same position.
