These worked perfectly in the SAI port on the front of a 12v VR6 cylinder head. I had a obd2 cylinder head that I'm putting on an obd1 VR. The port for the secondary air injection needs to be sealed up. I pressed 1 of these all the way in and a 2nd one that is slightly recessed. Can't beat the price for 10.
