The AEM 21-748C 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 Honda Fit 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 and engine breather line. 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.

April 26, 2016 - Part 21-748C
The 2015 Honda Fit Cold Air intake is awesome. Very fast to install and it looks great. It tidied up the engine bay getting rid of the fugly factory air box. The only issue I had was somehow I lost the 2'' rubber hose? (part number AEM-5-1002) I called AEM expecting to pay for another part and they are sending me a replacement no questions asked free of charge. Excellent customer service, thank you!
