1. Upon completion of the installation, reconnect the negative battery terminal before you start the engine.
2. Align the entire intake system for the best possible fit. Once the intake has been properly fitted continue
to tighten all nuts, bolts and clamps.
3. Periodically, recheck the alignment of the intake system and make sure there is proper clearance around
and along the length of the intake. Failure to follow proper maintenance procedures may cause
damage to the intake and will void the warranty.
4. Start the engine and listen carefully for any odd noises, rattles and/or air leaks prior to taking it for a test
drive. If any problems arise go back and check the vacuum lines, hoses and clamps that maybe causing
leaks or rattles and correct the problem.
5. Check the filter for excessive dirt build up. Clean or replace the filter with an original Injen filter (can be
bought on-line at “injenonline.com”). Congratulations! You have just completed the installation of the
best intake system sold on the market. Enjoy the added power and performance of your new intake
system.
