Product Description
The AEM 21-817C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Hyundai Elantra Sport models. The oversized cone-shaped AEM Dry Flow filter is made from an oil-free, synthetic filter media and can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). This system puts the air filter low and towards the front of the car where cooler air can be found. The 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's 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.

Designed specifically for 2017 and 2018 Hyundai Elantra models, this system replaces the factory air filter and intake housing, resulting in noticeable horsepower and torque improvements.

Built with durability and efficiency in mind, this intake system is backed by AEM's Lifetime Limited Warranty, providing long-term value and confidence in quality. Please note that some AEM air intake systems may not be legal for sale or use in California and other states with strict emission standards; verify vehicle compatibility and legal status before installation.
