If someone has some time, could you please measure the plug distance on an s5 or FD rotor housing? I would really like to know if this housing is compatible with anything available here.
Thanks ahead of time...

All s5 and up rotor housings are the same. The only difference with the s5 and the FD is that the FD rotor housings have a different coating on them from the factory and the area around the spark plugs offer better cooling supposedly. If you look at the Trailing plug hole on the outside of a s5 motor you will notice that there is a threaded hole above it. It is for a knock sensor and even the N/A s5 motors have these. S4 rotor housings don't have this and the knock sensor goes to the center intermediate housing. I've even used s5 N/A rotorhousings on turbo motors all I did was change out the exhaust isert sleeve. Timing is the same and you can find N/A rotorhousings more readily than Turbo housings. Hope this helps you out.
