The AEM 21-836WR 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 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 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.

Pleased!

I purchased two of these shelves. Both were received but one was a busted up return from another customer that didn’t get taken out of circulation. Parts were missing and damaged. Returned that for a replacement. It came in perfect. These are easy to put together, minus the pesky stickers that took a lot of patience, Goo Gone, and scraping to get off. I love the 2-tone of the black metal and brown wooden shelves and extra nice touch the middle shelf folds down.

Perfect shelf for the office
Size: 24 Inch, Color: Rustic Brown, Size: 24 Inch, Color: Rustic Brown
When we bought our house it came with an office space and this little wall space in between the cabinets lol. We had no idea what to do with it BUT our monitors took up so much room that we couldn't put anything on the desk really. Then we got the idea of a floating shelf and well this was perfect! Matches and really looks like it came with the house haha. It has held up and now I get my office supplies and can look at pics!
