The AEM 21-724C 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 is designed, tuned and dyno-tested to fit specific Hyundai Veloster Turbo models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the crank case breather hose and recirculation valve hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). 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.

So far I am very pleased with my purchase. It was easy to install and noticed a difference right away.

This product was perfect. Perfect fitment, no issues with clearance. Directions were clear and precise. After install, quick difference in performance and the sound of the intake sounds great, no drone effect or vibrations in the tube and no large whooshing noises while idling, which are usual with certain CAIs. Highly recommend this product. Great bang for you buck!
