Chevrolet HHR Spark Plug

While the nostalgic appearance of your Chevrolet HHR may take you back in time to the great American trucks of the 1940s, its performance keeps pressing on into the future. To keep your Heritage High Roof running like it should, upgrade to the correct type of HHR performance spark plugs from AutoZone.

Different types of engines require different types of spark plugs. Even though spark plugs all share the same basic function of igniting fuel to start combustion in your engine, your vehicle's manufacturer may recommend either hot or cold plugs. Installing the correct kind of Chevy HHR spark plug is important because a plug that gets too hot has the potential to ignite the fuel before the engine fires.
