AEM Induction Cold Air Intake Kits
AEM Induction cold air intake kits outperform every other cold air kit on the market. The difference is in their mandrel-bent aluminum or polyethylene intake pipe, which relocates the air filter outside of the engine bay for a cooler, denser intake charge. Unlike many other kits available, each pipe is individually tuned, in both length and diameter, to a specific application for maximum power gains. These AEM Induction cold air intake kits include an air filter, intake tube, and complete hardware kit. Order the model designed for fitment and best performance on your specific vehicle.
