The Bosch side fires are an AAN plug that has a removable top. I will probably use those, they worked great with my B5 S4.

Pros: worked great

Every time I fill up I check my mileage, I could never get great MPG from the FR8DS, but the coppers were way better MPG wise. Throttle response was less as well. The Silbers always looked more sooty during inspections than the coppers. The silver plug will last longer.

Pros: longer service interval

Cons: poor MPG, less throttle response, looked sooty

Part number: FR8DS
