The Forge direct replacement blow-off valve is designed to be a more durable and performance oriented valve than the OEM unit. The OEM valve is suitable for stock boost levels for a period of time, however, once boost pressure is raised, and after prolonged use, the stock valve will no longer be adequate. Raising the boost output of the vehicle will have a number of effects on the OEM valve. First and foremost, the additional boost pressure will quickly exceed the capacity of the OEM spring to keep the valve closed under higher boost levels. Since you cannot change the springs in the OEM valve, it cannot be adjusted for higher boost levels. Secondly, the additional heat generated by the increased boost will quickly deteriorate the OEM rubber valve diaphragm, which will also lose strength with repeated oscillations.
The Forge valve uses full billet aluminum construction and Viton silicone o-rings that will withstand the highest boost levels and repeated abuse. It is also tunable for varying boost levels with the included spring tuning kit. If there is ever a problem with the valve such as a torn o-ring, replacements are available free of charge, and the valve is fully rebuildable.
As the Genesis Coupe 2.0T does not use a MAF (mass air flow) sensor, there is no reason that the residual boost pressure at throttle lift cannot be vented to the atmosphere such as with this valve. The engine management does not meter the air volume entering the engine, so this residual pressure can be discharged without any adverse affects on the performance or driveability of the vehicle. Additionally, the valve being open at an idle or vacuum condition is a normal occurance, and is not indicative of a leaking valve. If the intake manifold is in vacuum, even while cruising at speed, the valve may be open. The OEM valve operates in this same manner, however, it is just not visible/audible because it is recirculating instead of vented to the atmosphere. Using a stiffer spring to keep the valve closed at a vacuum condition may result in too stiff of a spring tension to effectively discharge pressure at a throttle lift condition.

Very easy install it takes about 15 min great product I would highly recommend Scott on 29th Dec 2016
Really easy to install even if your not experienced. Sounds perfect. Exactly what I was looking for! Mjbemont on 2nd Jun 2016
Fast shipping, great bov, not too obnoxious, but still loud enough. Easy installation, took about 30 minutes! Alex on 18th May 2016
This is the first bov I've installed on a car and the install is simple and straight forward. It has a great sound after letting off throttle in boost. 5/5 Unknown on 18th Apr 2016
I just installed today, and so far I have been loving it. I am already running a K&N intake and coupled with this BOV, the turbo sounds like like it should and not have the same echoing type sound that was present with the stock recirculation valve. when let off the gas. I was also pleasantly surprised to find out that I noticed a slight increased in performance as it seems that it holds boost for longer period of time.
Overall very satisfied with the product and I will see how it does down the road. Jon on 13th Mar 2016
Nice bov great upgrade. Not as loud I would've liked but its still loud enough. Great quality. Install on my 2013 was simple. Unknown on 20th Feb 2016
