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. Comes with limited lifetime warranty.
