Using this Injen intake is easy. First, make sure your vehicle's engine is cool. Locate the old intake system and carefully remove it. Then, install the new Injen intake in its place, following the included instructions. For best results, check the air filter regularly. If it looks dirty, clean or replace it. When installing or removing the intake, be gentle to avoid damaging any parts. Also, remember to double - check all connections to ensure they're secure. If you have any problems during installation or use, refer to the product manual or contact customer support.
