Upgrade your Toyota pickup or 4Runner with the K&N 57-9006 Performance Air Intake Kit, designed to optimize airflow and improve engine performance. This system replaces the factory air filter and intake housing with a high-flow design that significantly reduces intake restriction. By smoothing and straightening the airflow, the intake allows your engine to breathe more efficiently, resulting in increased power and acceleration across the RPM range. The kit includes a chrome-topped K&N high-flow air filter, which can provide up to 100,000 miles of service before needing replacement, depending on driving conditions. The intake tube is engineered for optimal aerodynamics and directs air seamlessly into the throttle body while accommodating the factory mass air sensor and engine vent line, ensuring compatibility and ease of installation.
