GFB Hybrid Dual-Port Blow-Off Valve

Valve was an easy install for the I20N took about 2 hours. some people say go from the bottom or go from the top. I went from the top as I'm limited for equipment and that's where the bolts are.
When on 50/50 with whistle trumpet you won't really get a whistle. you will however obtain a whistle when changing to full atmospheric. I played around with the adjustment of the spring for about 30 minutes to unsure I wasn't hearing the pshhh at a low throttle input.

Overall, good purchase, good noise.

When will this be restocked? I made an order of this unit on 27th may and I'm still waiting for the tracking number. Items are paid and status are unfulfilled at the moment. it's my first time ordering in CherryTuning so I'm kinda confused on what should I wait for now 😅

I have it at 50/50 recirc and venting and the sound is nice, easily heard inside the cabin. Not too obnoxious at 50/50, I imagine 100% venting is quite loud. The install is tricky however. Removing the hose from the stock valve is difficult and a lot of force is required, after releasing the metal clip. It took me about 2 hours to install.
Install suggests from the top, and I managed to install from the top. Many people struggle, but I have quite small hands so was able to do it, after removing my intake.

Pros: almost exactly what I wanted, have the sensitivity turned down and it’s not obnoxiously loud. Able to drive it without it going off in a load way. I’m running it with a Cherry Tune.

Cons: instructions included suggested installing from top of the engine bay. I’m disputing that it’s possible to do this , but if you go from the bottom you need a safe way to get under to do the work.
I ended up getting it installed when it was getting the ECU/TCU tune , so maybe include this in your budget consideration. This doesn’t change the fact that the product is well made and I like it but the instructions from GFB should probably be updated with a second option that is more realistic for the DIY-er.

I purchased this as i was after some extra intake noise. Was very easy to install on my 2020 i30 N-Line i highly recommend do it from under the car instead of from the top under the airbox, i had more luck getting the bolts from underneath.

I had it on 50/50 and even that was a tad to loud for my liking being that the ECU decides when to blow off i was getting some pretty loud pssshhh at very low speed and rpm, checked the hoses thinking it was that but it wasn't and I adjusted the spring pressure but ended up going to full recirc at the end of the day. ( i think i am just getting to old)

Fantastic product and great build quality but for anyone out there looking for fine tune ability just remember this is 0% - 50% - 100% if you dont like the noise at 50/50 you options are limited but that is why they make a full adjustable version!
