Re: spark plug change interval for expensive plugs

Just my .02 cents, but in my experience, Bosch plats suck nard.

Every engine I ever put them in exhibited jittery idle and cold start difficulty.

I had people pay me to pull them out and replace with OEM in the shop.

I'd suggest ND or NGK plugs, and don't use plats if not called for originally. They never seem to improve anything, and sometimes cause minor performance issues.
