I've been thinking about getting a helical throttle body spacer to add some hp to my 7A-FE engine, but I have some questions. First off, can anyone tell me if they actually work? I don't want to end up wasting $. If they do work, can anyone tell me where to find one that's made for the 7A-FE? I've looked all over and I can only find ones for the 5S-FE. Alternatively, can anyone tell me if I can just use one for a 5S-FE on my 7A-FE? perhaps they have similar throttle bodies.
