Iridium plugs usually have a longer lifespan and better performance at high temperatures. For example, iridium spark plugs can last up to 100,000 miles compared to copper plugs, which may require replacement every 20,000 miles. As noted by Delco Remy (2020), using the appropriate material based on riding conditions and frequency can lead to a more reliable ignition system.

4. Engine Type Compatibility:
   Engine type compatibility is essential when choosing spark plugs. Different engines require spark plugs with specific characteristics, such as thread size and gap size. High-performance engines often need specialized plugs for maximum efficiency. According to a 2018 report by the Motorcycle Industry Council, mismatch of plug type can lead to poor performance and engine damage. Therefore, it is important to consult the motorcycle manufacturer’s recommendations to ensure the selected spark plug aligns with engine specifications.
