Comes with photos and spark plug gap taken as proof. Easily 30,000 ~ 40,000 km for the copper plugs on my car.

Bro, im using OWS spark plugs.. should the spark plugs last longer than normal ones?

no definite answer

 

good plugs can have bad apples

good plugs can be spoilt by lousy fuel eg constant truly asia fuel

lousy plugs can last long if used in the ideal conditions

 

end of day, play safe check every 20k, or at most 40k

Examined those copper electrodes spark plugs on my previous Kelisa after 50k km to be in order. Re-installed them since no sign of wear for replacement

You will get misfiring. Once you get that, it means your gap is too big already. Need to regap the plugs provide the center and grounding electrode still in good shape.

I'm not familiar with OWS plugs, so no comment.

Spark plugs life depend on the particular engine type, how it is driven and any modification made. Better to check the condition yourself to judge how long it can last, visual inspection and measurement of the gap by feeler gauge.

OWS iridium according to my WS need to change at 20K. Last used NGK iridium for 45K I keep as wear not so much.
