life span of spark plug?

[prodigy]

I remember paying like RM20/pc of Bosch Super 4 plug. Are you sure its that cheap?

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.

i use oem plugs with manufacturers recommended plug gapping and heat range. change it every 15,000-20,000km.

 

[g88]

yeah..heat range play important role in your car performance...too cold or too hot plug is not good for the engine combustion
