K&N 16-17 Nissan Titan XD V8-5.0L DSL 63 Series Aircharger Performance IntakeThe K&N AirCharger 63 6017 air intake system replaces your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake air restriction as they smooth and straighten air flow. More air means more usable power and acceleration throughout the engine's RPM range. The 63 6017 air intake comes with a large chrome topped K&N high flow air filter and a heat shield that mounts onto the inner fender.
