Several Misfire 4.8i

Wtf is wrong with the quote button?

Unicorn is correct, the 4294 is the OE Laser Iridium Plug. 6441 is the Iridium IX. 3271 is the Double Platinum. 7100 is the G-Power Platinum. 4291 is the V-Power Copper.

Where did you get the 3199 from? Did some shop recommend it?

Only use the OE 4294. Some of the ones on the NGK site fit but are not compatible.

All of those listed should work, their lifespans will vary though. But yes I would also recommend only using the 4294 which I mentioned is the OE replacement.

That’s just it. They don’t all work but they do fit. I used one of the listed ones on my 4.8i. Threw misfires everywhere. I contacted NGK and the shop I bought them from damaged them out in the return and I bought the OE 4294. Fixed it all.

LOL...75% of the time the quote doesnt work on this website. Annoying.


1. Manufacturers, as in PLUG manufacturers, may say it is the right' plug, but that is only their opinon. The fancy, advanced designs are not OE....and while NGK may say they work, they may not. Subtle differneces in temp, cooling, flame-wavefront, etc, can happen in some BMW engines


2. FI (turbo) motors are MUCH more susceptible to these plug issues. I think timing is tighter AND thermal effects at the combustion point become more critical.


FWIW

When I say the right ones I meant that I did not use NGK 3199 like I tought. I used bosch 0 242 235 776. So spark plugs are not the issue.

I think you must have a bad sensor. Or a computer having issues using info to provide the right fuel to air mixture.
