spark plugs?
 
Anyone know anything about the BOSCH +4 spark plugs? Good , Bad, waste of money? Please let me know

I've had bad experience with the Bosch platinums, lots of missfires. Are the +4's the ones with 4 electrodes? Thats good longevity, bad performance. The spark is too shrouded. I've also used AC Delco Rapidfires, I saw no difference from running stock plugs.

AC Delco MR43T and runs flawlessly! Never tried the BOSCH plugs before, I just stick to what works.

From what I understand, you get better performance with non-platinum plugs. Platinums just last longer.

Thanks, I guess I'll stick with AC Delco
