We are selling this one off custom Jeep 2.5 four cylinder aluminum sheet metal intake manifold. This was made so we could dyno a custom built motor with a carb. We made a custom bolt in "Turtle" to aid in fuel distribution on a carb application. You could add injector bungs easily with an adapter plate and retro-fit this one to efi. This will fit a stock head and the Turtle unbolts.
