I had a need for a low buck method to bolt on stock intakes where CIS once lived. If you have a CIS Engine you know there is a notch in the port in the head that factory intakes do not cover correctly. I searched around the net and other popular forums. The only resource I came up with were PMO intake manifolds for $ 450.00.

I decided to manufacture an option. These are Alien Adaptors. They fit the heads, clear the shroud and make it possible to run your stock intake manifolds. I have them in both "S" head port size and non "S" port size.

$ 80.00 shipped in the CONUS. Send me a PM
