Best automotive tuborcharger blow off valves according to redditors

Way too expensive IMO. Here's one for $99

That'll save you enough for this quality blow off valve

Get something like this and install it on the pipe between the intercooler and throttle body.

Make sure the flange matches what you have currently

I'd recommend against modifying the intercooler.

Sounds like you have a bad bypass valve. Time for an upgrade. Just buy a blow off valve and replace it. Easy install.. Takes about 20 min, if that.

My OEM BPV was developing a small leak so I went online and purchased one of these. Doesn't really do anything special but it definitely seals up nice.

There are other ones out there but this one was the most reasonably priced options I could find.

edit: oops forgot to find a means of boost control.. any suggestions?

No none at all. It's honestly the perfect amount of noise. Loud enough for me when I want it, but quiet when I want it quiet.

The bov I have is www.amazon.com/Turbosmart-TS-0203-1061-Blow-Off-Valve/dp/B00IGWW5UC

Very easy install. Placement of BOV is behind front right wheel.

Turbosmart TS-0203-1061 Blow-Off... https://www.amazon.com/dp/B00IGWW5UC?ref=ppx_pop_mob_ap_share

The dual port shortie is the 100% recirculating BOV. There is no ventilation into the atmosphere so you will not get the “pshhhh” sound when you close the throttle.

Where are you seeing $250? CJ has it for $170, and its $157 on amazon.
