The AEM 21-730C 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 Genesis Coupe 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 and is protected by a heat shield with a replacement fresh air adapter scoop 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 air temperature sensor, engine breather tube and sound tube. 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 easy to install with commonly available tools and it 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.

Very satisfied with this intake by AEM. My car definitely sounds better and is a lot more torqueier.

I must say that the installation was a bit tricky and my order was missing the rubber trim, but overall a product well worth the money. I can definitely see an improvement off the line and it has a great aesthetic value to the engine bay. Also, customer service was quick on sending me out the part that was missing and when that arrived they sent another one being that the one received was too long. Overall, I would totally recommend this product.

Intake is great. Looks awesome, works great and was very easy to install. Took about 20- 30 minutes, most of which was just getting the stock equipment out. Thanks.
