Our blow-off valve is made from billet aluminium, this atmospheric valve blows air to atmosphere creating the "Whoosh" sound most commonly associated with rally cars. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

This blow-off valve is dedicted for TD04 turbocharger with stock DV nest. Please make sure You have about 70 mm of free space around stock DV nest in order to fit this Blow-off valve.

The harder spring is supplied separately for self-installation, is designed for higher than stock boost level.The soft spring is already installed in the valve and will be perfect for 90% of applications.
Blow off valve is supplied with two valve springs - a soft spring and a hard spring.

Twin piston construction allows use this with most cars with MAF sensor where single pistons valves can cause ECU errors.
We cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.

Note: We recommend installation of the valve by a specialized company. Blow off is dedicated to track use and sports cars. The blow-off valve, installed instead of the stock DV valve, may cause a check engine error. If this occurs, remap should be performed to adjust ECU to change done in the intake setup (disable check engine errors permanently).
