boy is it rare when I call a company out by name - but given the cost and aggravation. It's time. Never, ever buy AC delco spark plugs. Whether unobtainium or their copper core, the housings crack and will cause you no end to trouble. I just replaced plugs on my H3 Hummer, one was bad. It ate 3 coils before I finally figured out what was going on - easy crack to see (bastards). Follow this up, I have an FJ40 with a 350 chevy in it. I kept going through ignition modules. 5 of 8 plugs are cracked. The H3, the plug was brand new. The FJ40, 1000 miles.... run away from them, they want to save money making that stuff in China - why should I have to bear their R&D and quality testing?
