GFB Hybrid Dual-Port Blow-Off Valve

Nice gear

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.

Great Product, Australian Made.

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!

Great product sounds awesome was tricky to install as im a noob haha.
