Spark plug Bosch or Motorcraft
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.
I've been using bosch FD5POR aka rs2 plugs. I'm quite pleased with them.
Bosch F5DP0R on a T3/T4 50 trim at 25psi daily. Love it.
I've been running BOSH+ and it feels great!!
I've used Bosch plugs for many years all types and never ever had one single issue.
I've used nothing but Bosch in my 2L and never ever had any issues.
Bosch FR8DC+ perform well and you won't have to worry about seized plugs. You might have to change them sooner.
iv had mor problems with a brand new bosh plug then any other plug.. even cheap knock off checker brands...
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.
Do not use the Silber plugs. Mileage and performance suffers.
