AEM Cold Air Intake Systems are designed to produce horsepower and torque gains. They replace the restrictive factory airbox and air filter to give you better performance and better engine sound. AEM cold air intakes relocate the air filter outside the engine compartment so cooler air can be fed into your engine. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber for more horsepower and torque. AEM Cold Air Intakes include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. They include a mandrel-bent aluminum intake tube and high quality hardware designed to reduce restriction and reduce intake temperature. The design and components of each intake system vary so consult the installation instructions for more information on the contents of each part number. This Air Intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

It fit my 2013 Jetta 2.5 SE perfect. Very easy to install. Took me about 45mins to put on my car. Very nice sound and performance boost. It also increased my MPG. Very well made. This is the second AEM intake I have purchased and I will buy more. The only problem I have is that when it was shipped, it was in the original box for everyone to see, as it laid on my front porch. Good thing I live in a good neighborhood.

I ordered 21-733C more than a month ago and so far over 1000 miles passed with that intake. What I like: Engine sound - Between 2000 - 3500 there is a nice deep sound. Unfortunately it's not really consistent. Almost easy installation - only thing bothered me - 2 additional air injection tubes. They fit very hard and I broke one clip on larger side (You can see that from the picture) Looks very nice. Dry filter. What I don't like: Only one thing, - What so called sock or filter wrap costs $32? For the price of the intake over $275 you can expect to have this little and very cheap piece of cloth.
