Cold Air Intake Filter Kits
A cold air intake filter kit is guaranteed to improve an engine’s horsepower and torque performance. Aftermarket kits are designed to provide better airflow rates, cleaner air and in some instances boosted air that helps support turbocharger systems.
Most models are very easy to install, and a good kit will only require basic tools such as a screwdriver, plier and ratchet set. The time to replace it is around 90 minutes. The best replacement kits come with OEM style holes and connection shapes and sizes so that you don’t need to drill or adapt any part during the installation process. Kits are vehicle specific, so you do need to ascertain your exact model before buying and pairing a kit.
