Mint condition throttle body stacks and throttle bodies. Stacks are OEM 312 originals and throttle bodies are aftermarket guaranteed satisfaction. They are cast and machined aluminum from a German source. If you are not satisfied with the latter you can return them and get you money back. Personally I think they are better than OEM throttle bodies. Everything needed is there including the microswitch, pushrods, and injection line holders. New clips, hoses, and throttle body bell crank. The pricing is $4900+shipping for the set and I will consider separating them if the price is right. I take Paypal at pkg911porsche @aol.com.
