AEM R56 "S" Intake: N18

AEM intake for the Gen2 R55/6/7/8/9 Cooper S models with the N18 engine which was used on the 2011 and newer S models. Please note that the JCW engine stayed as the N14 into 2012 but the "S" model engine changed to the N18 in 2012.

The AEM intake is a two part design which includes the hood mounted air funnel to pull fresh air through the hood scoop and the main intake assembly that replaces the factory airbox. This is very similar to the DDM race intake but is entirely plastic which does not hold heat as long as metal and will not rust. Once installed the only upper stress bars that will fit are the GT spec and the AEM bar.

The AEM 21-721C 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 the N18 engine. 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 replacement air box with a fully-opened hood scoop which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable black 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 vacuum line port. 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 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.
