a standard spark plug should last 10-20K KM...those better/performance type should last 30-50KM....
Spark plug is wear and tear part...
Also life span of spark plug depend on your engine condition...if your engine makan engine oil / wrong tuning then your spark plug will wear out faster.
Hi ECR33 GTS Series 2 owners,
Let me know if you are looking for a vented fiber bonnet, I am looking for an original one to swap, this fiber one is light but I prefer the original one, thanks.
