Upgrade your engine's performance with NGK Iridium IX spark plugs. Designed for performance enthusiasts, these plugs offer outstanding acceleration, high fuel efficiency, and long - lasting durability. They provide extreme ignitability and excellent anti - fouling properties. The tapered cut ground electrode enhances starting, idling, and throttle response. The Iridium fine wire center electrode, six times harder than platinum, and the high - melting - point Iridium alloy are perfect for modern engines. For even better performance, consider upgrading to an NGK Ruthenium HX plug. This part fits a wide range of vehicles including Acura, Chevrolet, Chrysler, and many others from different years and models.

Using the NGK Iridium Spark Plug is easy. First, make sure your engine is cool. Remove the old spark plugs carefully using a spark plug socket. Then, install the new NGK Iridium Spark Plugs, tightening them to the correct torque. Don't overtighten as it may damage the plugs or the engine. When it comes to maintenance, these plugs are durable but it's a good idea to check them regularly for any signs of wear or fouling. If you notice poor engine performance, like rough idling or reduced acceleration, it might be time to check the spark plugs. Also, store the plugs in a dry place to prevent corrosion. If you want to take your engine's performance to the next level, you can think about upgrading to an NGK Ruthenium HX plug later.
