GETTING STARTED
-
Turn the ignition OFF and disconnect the vehicle’s negative battery cable. If the engine has run within the past two hours let it cool down.
NOTE: Disconnecting the negative battery cable erases pre-programmed electronic memories. Write down all memory settings before disconnecting the negative battery cable. Some radios will require an anti-theft code to be entered after the battery is reconnected. The anti-theft code is typically supplied with your owner’s manual. In the event your vehicles’ anti-theft code cannot be recovered, contact an authorized dealership to obtain your vehicles anti-theft code. We also highly recommend NOT discarding any stock parts after the installation. -

Final Steps
Once the intake has been positioned and checked for clearance, tighten all of
the clamps and secure all of the parts.
Upon completion of the installation, reconnect the negative battery terminal before you start the engine. Double check to make sure everything is tight and properly positioned before starting the vehicle. Start the engine. Let the car idle for 3 minutes. Perform a final inspection before driving the vehicle. 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 may be causing leaks or rattles and correct the problem. Periodically, recheck the alignment of the intake system and make sure there is proper clearance around and along the l ength of the intake. Failure to follow proper maintenance procedures may cause damage to the intake and will void the warranty.
