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.

It's works amazing, easy install and comes pre grease love it Alex Soto on 7th Aug 2017
Love the sound it makes and very easy to install. Delivery was quick and the product does exactly what I want it to... breaking necks ! Robert on 26th Jul 2017
This BOV has a great design and good sound, It is a little louder than I was expecting and annoying to install without the proper tools but It is worth it for the added boost pressures over the cheap stock one. JT on 11th Jul 2017
After installing a straight thru Intake & 3" diameter tuned single turbo back exhaust,
was I in for a surprise!! Looking into the sound dimensions, When I started the car the first time,
Mama Mia, I thought I had broken something or left some thing in the intake. To make the sound appropriate, I figured out driving while making the noise subdued, I hadn't heard the car
from outside until recently a tech Guy (good) drove it through a couple of gears in the mid to high rpm range. Outrageous in not such a cool way.., , , The car sounded like "if your Genesi
coupe sounds so intense, "what is under the hood?"
The Forge BOV made the car sound normal after warming up. Sounds like normal 2.0t from outside the car. Excellent design in "Form Follows Function", Just a whisper from the BOV. Nice+ Michael on 10th Jul 2017
One of the easiest mods I've ever done. Good quality material. Unknown on 8th Jul 2017
I still cannot believe how fast this arrived - installation was not bad at all, end result put a smile on my face immediately! Only two pieces of feedback I have is actually for the manufacturer - may want to include a spare on the hardware side. That lower bolt is in a bad spot for allen wrenches - ended up losing it in the bay somewhere. Regardless, awesome product and amazing delivery. Vincent C on 26th May 2017
