Infiniti Q45 Spark Plug

You enjoy taking care of your Q45.

Select Your VehicleIt's not all the time that you discover you need a replacement Spark Plug to fix your car or truck. Your Infiniti dealership isn't the only place to locate the highest quality parts to repair your Q45. When your Infiniti Q45 was born, it was destined for a person with discerning taste who prioritizes Japanese engineering in their automobile. Infiniti vehicle drivers have come to expect a certain level of a reputation for safety when driving their Q45 around town.

Don't go too long without fixing your Spark Plug... here's why.

Sometimes the most important performance parts are the smallest, but they aren't considered when there's a performance problem. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your Infiniti Q45 spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. When one of the spark plugs does not fire when it should, the engine in your Infiniti Q45 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
