The AFE 51-81262 Pro Dry S Magnum Force Stage 2 SI Intake System increases flow and performance in your 2008-2010 Ford 6.4L Powerstroke. This aFe Stage 2 sealed cold air intake produces up to 28 HP and up to 54 lbs. x ft. torque while out flowing the factory intake by up to 41%. Fully sealed in a durable commercial grade designed rotomolded air box, this air intake system features a 5-1/2" Pro DRY S washable/reusable, high filtration conical air filter that provides maximum filtration (99.2% efficient) and convenience (requires no oils to clean). This intake system features a heat-insulating molded plastic intake tube and a unique turbo adaptor that funnels air into the turbo for improved volumetric efficiency and maximum performance while lowering Intake Air Temps (I.A.T). The "oil-free" Pro DRY S performance air filter is constructed with 100% polyurethane for long life and multiple cleaning cycles. Utilizing factory mounting points, this system is easy to assemble and easy to install. Fully Sealed Design aFe engineers have designed a very sophisticated 2-piece sealed intake housing that keeps out warm underhood air and brings in cooler, outside air for a denser intake charge.
