The Banks 42220 Ram Air Cold Air Intake is a high-performance air intake system that has been extensively tested and validated to provide superior airflow and filtration. The enclosed housing keeps out hot, power-robbing engine air, while the giant filter maximizes high-flow filtration. This helps the engine run cooler and extends its service life. The 5 inch bellows prevents component damage, while the cooler temperatures and cleaner-running engine result in reduced exhaust gas temps (EGTs). The Banks Ram Air Cold Air Intake comes with a 5-year limited warranty (filter: lifetime limited warranty).
