Intake Valve Cleaning Adapter
This adapter was made so cleaning the backs of motor intake valves isn't so messy. After cleaning the backs of the valves of hardened carbon deposits, this is placed over the open port with a vaccum addached. Then a shop-air pistol is inserted to the hold on the right.
The blasting of air causes the loose carbon to fly around in the port while the vaccum sucks it up. Now very little cleanup time is needed around the work area. Time is money arter all!
The one here I made is specificly for the Audi 1.8 and 2.0 Liter CDxx series motors.
