Improve throttle response and power in your vehicle with a K&N 57 Series Aircharger high-performance cold air intake. These high-flow intake kits provide better air flow to your motor by replacing the factory air path with a larger diameter polyethylene tube. This charge of fresh air allows your motor to breathe better and immediately put out more power!

All 57 Series high-flow intakes include the largest conical high-performance filter that will fit in your engine compartment and still use OE holes and mounting points. The bigger filter surface area also allows more air to flow into the engine and captures more dirt, boosting service intervals up to up to 100,000 miles.

Note: Some K&N 57 Series systems won't not fit on applications with lift kits.

aFe MagnumForce Stage 2 cold air kits replace the factory intake hose, air box and filter with the largest possible parts while still retaining the factory mounts. The larger intake hose, air box and huge aFe air filter provide more fresh, cold air to your motor which creates more power. Also comes with the largest aFe filter possible inside the new air box. aFe filters are easier to service than oil-impregnated or foam filters - simply tap it, vacuum it or wash it with soap and water to clean.
