aFe FULL METAL Power Stage-2 cold air intake system that replaces the factory airbox lid and inlet tube with a black powder-coated heat shield and an aluminum intake tube. The heat shield snaps onto the lower half of the factory airbox and uses the factory mounting points, and a 3-angle adapter speeds up the air leaving the filter. The 4-1/2 in oval conical filter has an inverted top and uses Pro DRY S three-layer oil-free synthetic media that is washable and reusable. It flows 385 CFM at 7 in H2O, 79% more than the factory intake, and is rated at up to 5 hp and 7 lb-ft over stock.
