Standard OEM air recirculation dump valve in plastic for Lancia Delta integrale 8v, 16v, Evo 1 & Evolution 2. Other ref 82468490.

This atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

Machined, aluminium, vent to atmosphere, piston dump valve.

Suitable for boost up to 1.3 Bar & a stiffer spring is included for 1.3 - 3 Bar competition cars.

Ragazzon performance exhaust de-cat pipe. Stainless steel direct replacement to the factory part (standard diameter). Fits cars with a factory fitted catalytic converter.
