Description

Magnum FORCE Intake

Sealed, molded plastic or aluminum cover provides factory style with less intake noise than open systems. Our specially engineered air box openings pull cold air from outside the engine compartment increasing engine efficiency and producing greater performance gain. The cross-linked polypropylene rotomolded plastic air box replaces restrictive stock air box and ensures a consistent supply of cold fresh air; built-in ram scoop forces cold, outside air to filter. Precision designed molded plastic intake tube maximizes airflow volume and speed for optimum power gains. 360 degree flow, washable and reusable, limited lifetime filters are high flow and high performance.

Air Intake, Magnum Force Stage 2 Si Pro Dry S, Ford, Lincoln, 5.4L, Kit

aFe Magnum Force Pro Dry S Stage 2 Si air intake systems feed your engine clean, cool air—and lots of it! These systems feature fully sealed intake housings that keep out warm air under the hood and bring in cooler outside air for a denser intake charge. They're fitted with a heat-insulating molded plastic intake tube and a unique turbo adapter that funnels air into the turbo for improved volumetric efficiency and maximum performance, while lowering intake air temperatures. And, keeping the air clean is the patented 360 degree Pro Dry S performance cone filter. With three layers of fine mesh synthetic oil-free media and polyurethane construction, these conical filters will last a long time and through multiple cleaning cycles. Assembly and installation are easy, as these systems use factory mounting points. Flow maximum oxygen to your engine with these Magnum Force Pro Dry S Stage 2 Si air intake systems from aFe.
