The K&N cold air intake kit for 1999–2004 Toyota Tacoma and 4Runner with the V6 3.4L engine replaces the factory intake with a mandrel‑bent aluminum tube and a washable, reusable oiled cotton High‑Flow filter to increase horsepower and torque. Oversized filter service intervals extend up to 100,000 miles under normal highway driving; a heat shield helps reduce intake air temperatures. Check CARB status for California use.
