How long do copper NGK plugs last?
How long do copper NGK plugs last?
I picked up some NGK copper plugs about 7k miles ago from Autozone. Forgot the part number but heat range 6 and stock gap.
Should I get new ones? Haven't felt a drop in performance but it could have steadily dropped so I wouldn't be able to tell.

they should last about 30k if the motor is running right but if u feel a slight drop then replace them if u really want to they are cheap enough anyways like $1.79 so either way it wont hurt

yeah, they should last for a long while like mentioned above...i usually change them after 2 oil changes (4-5k miles) just because they are so cheap for a stock d16a6...
