For over 30 years, K&N has specialized in improving air flow to your vehicle's engine. Originally, they developed their high performance air filter to cope with the extreme demands of desert motocross racing, so you can be sure it'll stand up to whatever punishment you throw its way. And the K&N air filter performs at a level that ordinary disposable filters can't touch.

The secret? Several sheets of high-flow cotton gauze are sandwiched between two layers of aluminum wire mesh, then pleated and oiled to create a filter that offers increased air flow and excellent filtration. The K&N FilterCharger is washable and reusable, so your engine will be protected as long as you own your vehicle. And the K&N filter will not void your new vehicle's warranty.

The 33-2439 Air Filter fits your 2010-up Chevy Equinox and GMC Terrain with 2.4- and 3.0-liter engine. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle. This filter satisfies emissions requirements in all 50 states. Warranty: 10 years or 1,000,000 miles.

Product Research


Performance: The K&N High-Flow air filter is designed to give you up to 50% better airflow to your vehicle's engine than ordinary air filters. More air entering the engine can increase combustion efficiency, resulting in more horsepower and better acceleration.

Filtration: The filter has thousands of microscopic threads absorbing a specially formulated oil to create a powerful filtering medium that protects your engine from harmful contaminants.

Reusable: This K&N air filter is washable and reusable. Depending upon driving conditions, the filter can last up to 50,000 miles before cleaning is required. It is recommended that you clean and re-oil your filter every 50,000 miles, using the K&N Recharger Filter Care Service Kit (item # 513995050).

Million Mile Warranty: The filter is warranted for one million miles, or 10 years from the date of purchase, whichever comes first.
