The GrimmSpeed Cold air intake features an enclosed filter that protects incoming air from the hot temperatures in the engine bay. Perfectly designed to be a direct fit and requires no additional modifications. The intake tubing includes an air straightener which helps not only with the overall flow of the air, but ensures accurate measurements from your factory MAF sensor. Careful attention was taken when designing both the enclosure and the tubing to lower temperatures and maximize power.
