Color:Purple The Blow-Off valve (BOV) is a pressure relief device on the intake tract to prevent the turbo?ø??s compressor from going into surge. When the throttle is closed rapidly, the airflow is quickly reduced, causing flow instability and pressure fluctuations. Surge can eventually lead to thrust bearing failure due to the high loads associated with it. Blow-Off valves use a combination of manifold pressure signal and spring force to detect when the throttle is closed. When the throttle is closed rapidly, the BOV vents boost in the intake tract to atmosphere to relieve the pressure, helping to eliminate surge.Package Included:1 X Type-S Blow Off Valve Kit1 X Aluminum Flange Pipe

Do not run this useless you want chunks of metal in you engin!
See photos.Where to start? Metal debris all in this piece. Cylinder wall is gouged out and cracked. Vavle just hangs on gouges. Metal chunks on every surface that was cut. Rubber vavle inside was pinched and install wrong. No instructions for anyting. The only thing this would be good for is destroying a motor!

Sounds cool but leaks badly
Sounds cool but leaks like crazy. Im running a 5psi spring and was easily able to fully hit 5psi. Since install it maxes out at 2.5-3psi so I did a boost leak test and the valve was leaking a ton. Not a small leak like I can hear it leaking while boosting bad. it sounds like the valve doesn't know whether to stay closed or open when under pressure.

very nice
it comes with 2 weight springs.. simple to disassemble since i used the lighter springnote.. its a little odd the vac line connection is over one of the screws to remove the cap (for spring swap)fit and finish is nice.. comes with gaskets and tee

Great product and cool colors
Works great on my turbo 302 bronco. It blows off hard and loud enough at 7psi to hear over open downpipe. Has the classic super loud pshhhhhhhh sound

Leaks boost
For the price is fine... it leaks boost just by blowing it with your mouth imagine with the turbo... had to modify it a bit to stop it from leaks, but guess u get what paid for... also arrived faster than spected great service

Yes and no.
If you don't know how to tune or adjust boost on a car don't bother with this. I had to make modifications to the mounting flanges because the holes were about 1/4 in wider on the tube then the BOV. I disassembled the BOV as soon as I go it because I noticed the valve pressure was barely able to open with both thumbs. inside there were two pressure control springs. I removed the smaller of the two an reassembled the BOV. This kit also did not include the recirculation fitting that it shows in the picture. The seat for the valve is also of poor quality and I don't expect it to work for more the 5k miles. This be said the valve does work great if you know how to adjust it and what to watch out for. I currently am running 15psi with no issues and the valve modulates as it should. I would consider this a temporary part until you can afford a name brand BOV.

Atención!!!!!
No es buena calidad, materiales muy baratos y no tienen mucha vida útil, esperemos que funcione por un tiempo. Si o si un auto con turbo grande porque sino no llega a liberar la presión.
