Using this resonator delete kit is straightforward. First, make sure your car's engine is cool. Then, remove the factory air box and intercooler charge pipe resonators. Install the billet aluminum air box resonator delete plug and the intercooler charge pipe resonator delete plug in their respective places. Use the stainless - steel worm clamp to secure the parts. Important note: No ECU calibration is needed, so you don't have to worry about complex engine adjustments. For maintenance, regularly check the clamps to ensure they are tight. If you notice any unusual noises or performance issues, check the installation of the delete plugs. Keep the parts clean to ensure long - term performance.
