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.

Prom Must Have
Size: Large, Color: Black, Size: Large, Color: Black
1) Totally affordable compared to ANY rental
2) Prom or Homecoming, maybe a (non high fashion) charitable event type quality jacket. True to size.
3) Pants are likely a 36” length. But otherwise true to size. The quality is great.
4) I ordered according to another review. My son is 5’10” plus a smidge. He’s 180#. Athlete. I ordered a Large. It’s perfect other than the length. He has a twin brother who is the same height but about 20# lighter and would need a medium. Also an athlete.
6) Make sure you order in time for pants length alrerations.
5) Do it. Order it for your event. Save a few hundred dollars and a ton of time returning rentals, those pants can be used again for sure.

Great suit!
My man looked soooo handsome in his suit. We ordered this suit at the last minute. It fit perfect. He is 6'3 wears a 38 jean and xl shirt. We were worried about the length of the pants but they perfect and long and the jacket fit perfect! The quality was great and he said he loved the fit and it was spacious. We went to a ball and we leaned and rocked all night and he didnt have to come out of his jacket to do so.

The blue really pops
Fit fine, looks great, just wish it came with a tie. It does not come with a vest or shirt either but I didn’t really care about that. Pants were a little long but once my son put his shoes on he was able to manage length.

tuxedo
I bought this for my son for my sister's wedding.
The pants were way too big but we knew that when we ordered it.
We bought the correct sized bottoms and he rocked it.
