Fits 944 Turbo 86-89
Chances are if you have a 944 Turbo, the Compressor Bypass Valve (or what Porsche calls the Air Cut-Off Valve) needs to be replaced. This valve holds boost pressure when you shift gears so there isn't excessive lag while your turbo spools back up. Test your valve by removing the top hose and see if the valve will hold suction, if it doesn't, you need a new valve. Fits all 944 Turbo & Turbo S. AKA Bosch 0.280.142.108. |
