    fast 90 intake question

    Just bought a used fast 90 intake and I was wondering the best way to go from the 90mm throttle body to the stock 78mm MAF. Will the stock coupler stretch on out to 90mm or ?

    you can use the factory TB to MAF coupler.
    The TB's have the same outside diameter.
