50mm Blow Off Valve

The ZZP 50mm Blow Off Valve (of BOV) kit includes a high-quality billet aluminum blow off valve, weld-on flange(if selected), v-band clamp, and fittings. All units are tested for leakage and proper opening. Our 50mm BOV is unmatched at it’s price.

How to order your Blow Off Valve:

Version: 18" spring, the BOV will open with 18" of vacuum. This is recommended for most setups, including LSJ and 3800 turbo cars.
6" spring, this is specifically for the LNF because the factory PCM uses a solenoid to bypass boost to save itself.

Flange Option: What style flange do you need? If you purchase our IC pipes that come with a flange on them, you will not need to order a flange. We have aluminum, stainless and we even offer the BOV without a flange if you already have a pipe setup for it. The 50mm BOV shares the TiAl style flange.

This is a universal blow off valve. Does not bolt directly on to a stock turbo setup with a bypass valve like the Cruze, Sonic, ATS, or Camaro.

It's a good product

Was easy to weld quality metal for sure. I've done quite a bit to my buggy I got a 2008 Chevy HHR SS "Automatic" I just bought about a month ago I'm a little old lady in Indiana took vary good care of it drove it on the highway back and forth to Florida. So I started with suspension then motor mounts tranny mounts then I went ahead and did the new sensors which I got from you guys got charged pipes from Hahn, fabricated my own cold air intake as well as downpipe and 3in exhaust duals by the way coming out right in front of the back tires looks pretty cool sounds vicious I love it. And now it's time to start doing some tuning think I'm going to go with HP tuners. Honestly I was going to go through you guys for everything but I'm going to be honest when I called the first time the gentleman I spoke to and I'm not sure what his name was but he made me feel like a complete idiot and I even told him look this is my first time down the turbo Road .....but it's all good I'm over it. What kind of deals you got going on I need this ECU done as well as tranny tweek. It will be extremely difficult for me to actually come to you guys during the week because my hours at my job or 2:30 to 10:30 in the evening and as I understand it you guys aren't doing any like in person anyting Dino or anyting correct?
