This brand new JDM Style Polish Cold air intake with K&N high flow performance air filter replaces the stock restrictive air box and allows more and better air flow, thus increase horsepower & torque. The K&N air filter is placed inside the fenderwell and far away from the engine, getting the coolest air for maximum performance. This cold air intake kit includes the world's best K&N high flow performance air filter (which is pre-oiled from the factory) and the Polish 2.75" aluminum intake pipe. This intake kit also includes generic installation instruction, rubber coupler, clamps and mounting bracket. There is a MAF bung welded on the intake pipe so the stock MAF sensor can be installed. Installation is easy and straightforward. Installation time is approx 60-90 minutes. Tuning is NOT necessary but highly recommended after the installation of the cold air intake on the turbocharged vehicle.
