Brand new dump valve is for high performance applications with the desire to be noticed!
A new larger body and a beefier piston ensures the valve remains smooth under the most demanding circumstances.
This valve relieves compressor pressure surge caused by changing gears or backing off the throttle quickly and is designed for turbo charged engines running boost pressure. This is a direct replacement for the oem recirculating valve.
Please note this dump valve is not really loud, it makes a bit more sound than the standard one, check whether this item is suitable for your car before you purchase
