Key Features

• Included components: The kit ships with an air filter, air intake tube, silicon hose, silicon connecter and the pictured accessories so the installer has the core parts needed for assembly.
• Performance gain: The intake is engineered to reduce restriction and increase cold, oxygen-rich air reaching the engine, with claims of up to an estimated 14 horsepower and 13 ft-lb of torque under favorable conditions.
• Heat protection: A custom heat shield is included to help keep intake air cooler, which supports more consistent performance during spirited driving or towing.
• Reusable filter: The pleated cotton, oiled filter is reusable and rated for long service intervals, reducing waste and maintenance frequency compared with disposable paper filters.
• Durable construction: Mandrel-bent, powder-coated aluminum tubing and sturdy components aim to improve airflow and resist corrosion for long-term use.
