Girlfriends S4 T2 is running S6 housings. I thought S5 and S6 both have equally better than previous series chrome. Maybe @RotaryEvolution can confirm if I am right or wrong.

If you are going spanking new, get the newest series. Why the hell not?

 

Maybe I should edit my pictures to tell that they are EU-spec, so no one thinks I'm wrong?
This thread should help people, not confuse

 

fkin hell, oredered s4 n/a and s5 n/a housings from the us and they dont match. so i need a s4T housing to match s5 n/a housing and s5 turbo or s4turbo to match s4 n/a housing? this is getting more and more confusing and i really cant lose anymore money. ant btw what does the knock sensor do and do i need housings what both have knock sensor holes?

 

Okay can someone please confirm this. If i have two housings s4 and s5, (they have diffefent plug hole location) and if i order a new housing whatever it is s4 turbo or n/a or s5 the same then whatever it is it will match one of my housings what i already have. And do i need a knock sensor on both housings. The car will be turbocharged with a programmable ecu.
Sorry for confusing english.
