• Replacement is best done by a professional technician

The spark plugs within your INFINITI are situated in a line along the top or side of your engine. When you first see one, your Spark Plug may look like a large, bizarre-looking screw. Yet, this essential component plays a critical role in your vehicle's driving ability. If any Spark Plug becomes so worn that it no longer functions correctly, your vehicle may no longer run.

Your INFINITI spark plugs help your engine turn regular fuel into working energy, enabling you to move your INFINITI down the road with ease. During this process, your Spark Plug creates an intense electrical spark. This spark then ignites the incredibly combustible mixture of fuel and air in your combustion chamber, creating the energy needed to get your car moving. Without a properly functioning Spark Plug, the power your vehicle needs to ignite your fuel and convert it into actionable energy diminishes, which can result in critical problems.

A Spark Plug needs periodic inspection and servicing, much like motor oil and tire rotations on your car. If your Spark Plugs not serviced routinely, you may start to experience several signs and symptoms. Potential signs of an impaired Spark Plug include engine misfiring and knocking, reduced fuel economy, starting problems, sudden immobilization, and acceleration issues. All of these problems can stop your vehicle from working properly. Neglected spark plugs can also cause potential issues with many other engine components.

When it comes to replacing your Spark Plug, we suggest that you refer to your owner’s manual for recommended replacement periods. Most Spark Plug service intervals are suggested at the 30,000-mile mark.

Installing your Spark Plug yourself can be done but may be a bit difficult since you might need to disassemble your INFINITI's ignition cables, coil packs, plug wires, and other vital INFINITI components. We recommend leaving this work to experienced professionals. However, if you prefer to do the Spark Plug installation on your own, consult your car owner's manual, ensure that your vehicle is parked on a smooth surface, and unplug your car battery before starting this process.

Each vehicle demands a certain Spark Plug created with certain materials. Give your INFINITI what it needs to perform by replacing an impaired Spark Plug with authentic OEM components from INFINITI Parts.
