2000 A6 2.7T. Any reccomdations for spark plugs.
Iridium, platinun, U groove, multi electron. Has any one any experiance of different plugs in their cars ?
I'm not even sure what the standard plugs should be in my model.
Any help or advice would be appreciated.

Thanks

 

i just replaced mine with ngk double platinum. ill look for the product number and post later. either search here or look on an auto parts site and it will tell you what is OE. they are real easy to change aside from the front two (2 screws that can be a royal PITA).
