I've never had any experience with the Bosch IR plugs.... just the platinum. I think they must use the bare minimum amount of platinum to get away with calling them that. I've seen the center electrode worn all the way down so that it was recessed in the ceramic insulator, and the plugs were maybe a year old. The cheap copper Bosch plugs, as OEM in some german cars seemed to be ok.

First, anyone who says Bosch plugs are bad, is a foul. They are one of the largest manufacture of plugs for most European vehicles and when people say they are bad, very few if any of them have used them, it is all unfounded hear say.
That being said, if you want help with your misfire issue, send me your number and I'll call you

First, the electrode is all the way down to the porclean when brand new, that is their design.
More expensive plugs don't mean they are any better. If you are looking at new teck. plugs, the E3's are around $6 and out perform most of the newer plugs on the market.

Yeah, their bad design. After it wears a little, the electrode is buried deep inside the plug. If they truly had a measurable amount of platinum they wouldn't wear like they do, and they would cost more.

Check engine light flashing
I’ve Change plugs coils and wires. Check engine light is still flashing after I reset code. The only code I vet constant is misfire cylinder 6 but funny thing the coder reader gives me 2 codes for that misfire. Some times but rarely it will throw the code for random multi misfires. Also when I changed the coil packs I noticed there isn’t any locking clips on the connectors so they are just pushed on.

@Steven Hill Pull the #6 plug and take a look at it, if it was a bad connector you would get multiple misfires related to that bank not just 1 cylinder
