These AEM Induction cold air intake kits outperform every other cold air kit on the market. The difference is in their mandrel-bent aluminum 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, an intake tube, and a complete hardware kit.
