The E9X M3 doesn't need carbon cleaning, right?

There is no carbon or oil buildup issue with the S65. Last year I installed a new CF plenum and when I inspected the old plenum there was a very very light sheen of oil inside only (sticky more than oily). Just use premium fuels and don't worry about it.

An N55 would need 5-10 carbon cleanings by then. They get CRUSTY every 30k.

(2) cans of seafood and a gun bore cleaner. Take off the valves and dump a can down each runner and let it soak. Then jam a gun bore cleaner in those runners and spin it. Re assemble and take a drive to burn out all the seafoam. You will smoke like spy hunter for a while.

Run a bottle of cataclean through the system and repeat if necessary. This will help with carbon build up on the secondary air system.
