Choose from a variety of plug model numbers: IW - 24, IW - 27, IW - 29, IW - 31, and IW - 34. Remember, a higher plug number means a colder spark plug, offering you more options to fit your needs.

Using these Denso Rotax spark plugs is easy. First, make sure your engine is turned off and cooled down. Then, carefully remove the old spark plug and install the new one. Tighten it gently but firmly. When it comes to maintenance, check the spark plugs regularly for signs of wear, like dirt or damage. If you notice any issues, it's time to replace them. Also, keep in mind that a higher - numbered plug runs colder, so choose the right model according to your engine's requirements.
