AEM-21-814C
The AEM 21-814C 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 Toyota Corolla models. The oversized cone-shaped AEM DryFlow filter is made from an oil-free, synthetic filter media and can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). This system puts the air filter low and towards the front of the car on the drivers side where cooler air can be found. Cooler and denser air is then channeled through the mandrel-bent aluminum intake tube into the throttle body. The factory PCV and MAF sensor mount directly on the intake tube. Included is an extension harness for the MAF sensor and other hardware for installation. 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.
