    Hey guys, I have a 74mm S90 throttle body mating to a JMF drag manifold. The crappy gasket that came with the TB was torn on arrival. Any other options I have? I was thinking just going to a auto parts store and picking up some gasket material and making my own.

    That's typically what I've heard most people doing. I don't know of any pre-made gaskets available.

    The gaskets that come with the 74mm are really crappy. I use RTV and everything is good up to 40psi.

    We tried to source some to sell to guys that have removed/re-installed their S90 and want to go with a new gasket. We never could find any. Like everyone suggests, you may have to make your own. (At least until some enterprising company/individual decides to make them).
