21-817C AEM Cold Air Intake System, 1 Pack
The performance cold air intake system AEM 21-817C replaces your vehicle's restrictive factory air filter and air intake housing, producing horsepower and torque gains.
Designed, tuned, and dyno-tested, this air intake system fits specific Hyundai Elantra Sport models.
The oversized cone-shaped AEM dry flow filter is made from oil-free, synthetic filter media and can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions).
The air filter is positioned low and towards the front of the car where cooler air can be found.
Cooler and denser air is then channeled through the mandrel-bent aluminum intake tube into the throttle body.
The factory PCV and vent hoses mount directly on the intake tube using the existing spring clamps.
The air intake system is backed by AEM lifetime limited warranty.
Some AEM air intakes are not legal for sale or use in California and other States adopting California emission standards, while others are 50 state legal.
