Spark Plug Set - Audi / 3.7L V8 / 4.2L V8 / D2 A8 / S8 / C5 S6 / B6 / B7 / S4

Set of 8 Spark Plugs

Generally when one spark plug fails that means the rest will also fail soon. We recommend you change all spark plugs at once. That way a month later you won't be running a cylinder short because one of your other spark plugs failed.  


The Bosch Super Plus Spark Plug utilizes an yttrium enhanced copper core center electrode, making it one of the longest lasting copper core spark plug on the market - by 50% versus even OE plugs.

Bosch Super Plus also features a tapered, v-profile ground electrode for improved cold starts and better fuel ignitability.
