I hate audi forums, the are filled with so much useless banter. The stock Bosch plugs are freakin’ 15 bucks a pop. Anyone use anything else? ---

A plug is a plug really… As long as it’s the same heat range they are all gonna work ok, most plug “tech” is marketing … ---

Personal results, and the fact that a spark is a spark, as long as it starts combustion they will all work some plugs will run better on some cars based on ignition differancea, and everybody prefers NGk coppers( myself included) and they are dirt cheap… Iridiums/ platinum +4’s etc gnerally are all compromises for marketing a reason to sell a 20 dollar plug vs a 3 dollar one. ---
