Standard Issue Diverter Valves where designed with the Porsche 996TT in mind, using a side vacuum pipe to allow for easy routing inside an already crammed engine bay. These billet diverter valves dump charge-air back into the air intake system and keeps external noise to a minimum. Featuring a piston design which is superior to the factory rubber diaphragm, this DV allows for quicker throttle response, higher clamping load, and more reliable control of boost pressure. The units are machined from billet aluminum and come only in a stealth black anodized finish. As with all Standard Issue products we pride ourselves in function over form, with products guaranteed to perform.
**Will Also work in all VAG 1.8T engines, all VAG 2.7 Bi-Turbo engines.
