Bosch Spark Plug 7406 or 4417
It seems that there's been a lot of controversy around the plugs, and finding the proper part number (Bosch #7406 FGR7KQE0) wasn't as easy as it should've been.
My question is who has switched from OEM to the Bosch #4417 FGR7DQP on their AXQ V8 touareg (AXQ 4172 CC 4.2L)?
They seem to be used quite a bit in the Audi S4 v8 (4172 CC 4.2L) and vw phaeton (BGH 4172 CC 4.2L), which all seem to be very similar engines.
FAQ: What are the correct spark plugs for my B6/B7 S4?
