The intake is from GM Performance Parts and has been released to work with the new L92/L76/LS3 cylinder heads. This is an LS3 intake from the 2009 Corvette LS3. It comes complete with 39 Lb/Hr. injectors, return-less fuel rail assembly, 90mm drive-by-wire throttle body and MAP sensor. This intake will ONLY work with L92/L76/LS3 heads because of the port design.
