The AEM 21-478WR Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicles restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Subaru WRX, WRX STI, Impreza WRX and Impreza WRX STI 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 textured red powder coated finish. This air intake system was developed to accommodate the engines factory emissions control devices including the mass air flow sensor. The 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 AEMs 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.

    Real Review after 2 months
    Size: 3 Fl Oz (Pack of 1), Style: SPF 55
    Great and easy to use, because of liquid based. No need to reapply again for every 2 hours. Because I tried it every day

    Works great
    Size: 3 Fl Oz (Pack of 1), Style: SPF 55
    So no Sunscreen worked for me. I tried almost everything. Then I tried this one. Its seems pretty well. That absorbs the skin and does feel greasy. Very nice.

    No white film
    Size: 3 Fl Oz (Pack of 1), Style: SPF 55
    I am dark dark. So I was impressed with no white residue... a little goes a long way. I am not longer sun burnt. My skin looks much healthier.

    It's ok. Leaves a white cast and burns the eyes.
    Size: 3 Fl Oz (Pack of 1), Style: SPF 55
    Its good as it's not too heavy and definitely not greasy. However, it leaves a horrible white cast. And I have pretty fair skin. I have to use some type of bronzing drops before hand. Or put a tinted SPF moisturizer on top. It's pretty bad on that and it stings my eyes SOO badly I've had to wash it off! Burns that bad. So if your eyes are sensitive to sunscreen around the eyes. This will sting and burn, dont use it around the eyes if you can help it.
