QKPARTS For Volkswagen GTi Beetle Jetta Golf Audi A3 A4 A6 TT 1.8T BOV Blow Off Valve

Looks great, but DOES NOT WORK no matter how you adjust it! Do not buy...waste of money.

Decently well made and well machines but not functional. Maybe I got a dud, but it allows boost pressure right past no matter what the spring setting is. You can blow into one of the ports and it passes right through. Save up and buy the real thing.

The body and build of it is perfect, sounds great! The seal that comes with them are very wrong and cheap

Quality and works good no instructions but YouTube has plenty of videos. No check engine light, no running/idling issues happy with my purchase.

Not a bad little build but I had to tear it down and replace the seals before putting it on very weak seals other than that great valve still using it

Mechanic suggested it and it works perfect. Gives you the ability to have show (blow off sound) and go (more performance) or a little of both.

For the cash, it works well! No complaints

This is poorly made and is doesn’t work well I have leaks now. The rubber rings that came with it pop out when you tighten it up so that causes a leak. Wouldn’t recommend it.
