How many miles on 1 set of spark plugs?
Just wondering how many miles I should put on one set of spark plugs?
Currently, I'm running OEM 4 electrode copper plugs ($15 each at the dealer).
I've already put 78,000 miles on it without any effect on performance. Dealer said it will last upto 100K miles.
Appreciate any experience that you may have.
And celsdogg, they also say to change the engine oil every 7500 miles, but I think we all know not to do that. I actually change my engine oil every 2500 miles (4-5 months), since my car sits a lot.
Also, $15 per plug is really high. Just go to AutoZone or whatever you have in your area. They have Bosch +4 Iridiums for like $8 a plug. I just run the original one electrode plug, never had any problems with that.
