Spark Plug.

- 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 INFINITI spark plugs can be seen in a line on the side or top of your engine. At first glance, a Spark Plug looks somewhat like a large, misshapen screw. Yet, it plays a vital role in your INFINITI's ability to function. If your Spark Plug becomes so damaged that it stops working efficiently, your vehicle may not start or run.
Your INFINITI spark plugs and the engine work to transform regular fuel into working energy so that you're able to drive your INFINITI. So how does this happen? Your Spark Plug creates an electrical spark that ignites the extremely combustible combination of air and fuel in your combustion chamber. This process creates enough energy to get your car moving down the interstate. Without a great working Spark Plug, the power your vehicle needs to ignite the fuel and transform it into working energy decreases, which can result in critical issues.
Spark plugs require regular servicing and maintenance, similar to filters and tires on your vehicle. If they are neglected for too long, you may start to experience several issues. Signs of a bad Spark Plug are engine knocking and misfires, lower fuel economy, difficulty starting your INFINITI, random shut-offs, and acceleration issues. All of these problems can hinder your car from starting and driving efficiently. A damaged Spark Plug can also negatively impact your other engine parts.
When replacing a Spark Plug, we suggest that you read over your INFINITI owner's manual for scheduled replacement recommendations. Many Spark Plug service intervals are advised at the 30,000-mile mark.
Replacing a Spark Plug at home can be done but can prove a bit complicated as you may need to remove or disconnect car parts such as ignition cables, plug wires, coils and other critical components. We recommend leaving this job to authorized INFINITI experienced professionals. Should you choose to do the installation on your own, read over your car owner's manual, ensure that your car is in Park on a steady, flat surface, and unplug your battery before beginning the installation.
Each vehicle needs a particular Spark Plug created with proper material(s). Give your engine what's needed by trading an old or broken Spark Plug with authentic OEM components from INFINITI Parts.
