Re: spark plugs
Used to swear by Bosch platinums. Then all of the sudden they started running really hot and fouling out. This occusred in all my cars and caused spark knock in my 85 Caprice and a misfire code in a 97 Lumina. Seems the quality was deminished over time. Now I use the recommended Ac Delco stockers and enjoy not have any problems.
