The Chevrolet HHR, which stands for Heritage High Roof has a distinctive silhouette and a design that is reminiscent of the 1949 Chevy Suburban. Not a car, and not quite an SUV, the HHR crossover vehicle combines classic Chevrolet styling with modern convenience and versatility.

A vehicle as distinctive as the HHR deserves an equally unique Performance Air Intake System. K&N Engineering, not wanting to disappoint, has done just that. The Performance Air Intake System (57-3056) for the 2006 through 2011 Chevrolet HHR 2.4L L4 "Is the first time K&N has used an airbox in an intake kit," said Bert Heck, K&N Performance Kit Manger. This one of a kind airbox is custom engineered and molded from the same high-density polyethylene as our Performance Air Intake tubes."Designed for maximum air flow the unique airbox keeps the engine heat away from the open element air filter." For optimum performance 57-3056 retains use of the fresh air supply hose and "provides a cooler air charge," according to Heck.

K&N tests, on our in-house dynamometer, have shown a gain of 9.33 horsepower at 5325 RPM with the K&N (57-3056) Intake System. K&N Engineers were able to achieve such horsepower gains because the original factory airbox and original filter were restrictive. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten airflow. Restriction robs your engine of power and torque when you need it. When driving a vehicle as versatile as the HHR there is no telling when that extra horsepower boost is going to come in handy. It could be needed while merging onto the highway, or driving up a steep grade. K&N's Performance Air Intake System (57-3056) offers a horsepower increase no HHR owner should live without.

This air intake system uses a conical shaped chrome top high-flow air filter (RC-5149) and custom engineered molded airbox in place of the vehicle's restrictive stock configuration. The result is an air filter that captures harmful particles, provides more surface area, flows more air, and increases service life. This K&N air filter performs for up to 100,000 miles before service is required depending on driving conditions. Improving the air path between the filter and the motor is the rotationally-molded high-density polyethylene tube. It offers the most flexibility in design and outstanding horsepower numbers. It takes about 90 minutes or less to install this system with simple tools. It is covered by K&N's Million Mile Limited Warranty and is 50 state street legal.

The K&N 57-3056 air intake system fits the following vehicles:
2011 Chevrolet HHR 2.2L
2010 Chevrolet HHR 2.4L
