• Helps your engine convert fuel into useable energy
• Engine misfires, poor fuel efficiency, difficulty accelerating, and random shut offs are signs of a worn spark plug
• Replacement is best done by a professional technician

Your spark plugs are located in a straight line on the side or top of your vehicle's engine. At first glance, a Spark Plug looks somewhat like a big, oddly-shaped screw. In reality, it plays a significant role in your vehicle's overall function. If any Spark Plug becomes so worn that it ceases operating properly, your INFINITI probably won't run.

The spark plugs in your INFINITI and the engine work to turn fuel into working energy, enabling you to move your INFINITI down the road with ease. During this process, your Spark Plug creates an electrical spark that ignites the incredibly unstable fuel and air mixture in your combustion chamber, creating more than enough energy to power your INFINITI as it drives. With an impaired Spark Plug, the amount of force or power your vehicle needs to ignite the fuel and turn it into working energy diminishes, which can result in some pretty serious issues.

A Spark Plug needs routine servicing, just like filters and tires on your vehicle. If these components are neglected for too long, you may notice a few issues. Signs of a bad Spark Plug may involve engine misfiring and knocking, lower gas mileage, problems with starting your vehicle, sudden immobilization, and difficulty accelerating. Each of these troubles can keep your INFINITI from working properly. Neglected spark plugs can also negatively impact various other engine parts.

When it comes to replacing your Spark Plug, we recommend that you refer to your owner's manual for manufacturer recommended replacement periods. However, most Spark Plug service guidelines are advised at the 30,000-mile mark.

Doing a Spark Plug replacement at home is possible but can prove a little complicated since you might need to remove or disconnect your INFINITI's ignition cables, coil packs, plug wires, and other vital INFINITI components. We recommend leaving this work to mechanics and technicians. But if you do opt for doing the repairs at home, refer to your owner's manual, make sure that your car is in Park on a steady, flat surface, and unplug the battery before beginning the installation.

Each vehicle type demands a specific Spark Plug created with the appropriate materials. Give your engine what it needs to perform by replacing an impaired Spark Plug with authentic OEM parts from INFINITI Parts.
