There's plenty of room for both the TBS and the intake hose/connection. Actually more room with an aftermarket intake, however it'll fit fine with the stock intake or aftermarket because the hose from the intake to the throttle body and spacer are kind of accordion style. I think if you go to any of the TBS manufacturers websites, you can find lots of pictures of them installed.so would the TB Spacer not fit with the intake system ? curious b/c i'm going to be purchasing an S&B myself soon.
