Open up your engine's airways with the AEM Cold Air Induction System. The AEM Cold Air Intake is custom-tuned to boost torque and horsepower on your exact year, make, and model sport compact. Its mandrel-bent 6061 aluminum intake tube and Dryflow filter let your engine take in gulps of cool, clean air for tire-squealing performance.
AEM doesn't rest when it comes to designing their Cold Air Intake. They tune the length and diameter of every system to match the engine's resonant frequencies to let more air into the inlet valves. Plus, the filter is located outside of the engine compartment, so it draws in cooler, denser oxygen for superior combustion. This means more power for your engine across the whole RPM range.
Your AEM Performance Air Intake is simple to install, thanks to its included detailed instructions and full soft-mount hardware kit. It comes in four different finishes to dress up your engine bay. Your AEM Cold Air Intake System is backed by a Lifetime Warranty.
Note: For new model year vehicles the AEM Cold Air Intake may still be in "pending" status for CARB exemption. The exemption process takes time, but your AEM Intake will be exempt before your first emissions test.
