This electronic throtle body was also used on production LS7 cars up until 2007. This is a perfect throttle body for those of you that have LS1/LS6 powered vehicles and are doing the LS2 intake set up. It will fit any LS style 4 bolt intake manifold for example; LS2, LS3, LS7, L92, L76. This is NOT and WILL NOT fit a 3 bolt LS1 or LS6 intake manifold without an adapter. We use this throtle body on HIGH HP 2JZ or other boosted cars with MaxxECU , we supply o ring weld flange and contact to this throtle also .
