The AEM 21-732C 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 Subaru WRX 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 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 mass air flow sensor. 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.

Great!!! i loved the sound!!
If your looking for a high quality cold air intake for your wrx. I highly recommend this aem kit for your car. You will notice better throttle response. You will hear more engine noises as in the air getting sucked in, turbo spooling up and you can finally hear the blow off valve on your wrx. The more you step on the gas the louder the blow off valve is. Mpg is increased aswell. I’ve personally have gotten 47 mpg so far with it. Customer service at import image racing was awesome. It shipped out quick. And for the price you can’t beat it.
