Hello, Im going to have to do a rebuild on my S5 TII. I have a feeling that Im going to have a bad rotor housing. So, im wondering what all years, and models rotor housings will be a direct swap with my motor? Are S4 TII housings the exact same? Thanks

 

spark plug timing will be different between the series, S5 n/a rotor housings should be able to be used if modified correctly if you can't find S5 T2 housings.
