I found that the airbox mod is worth doing: I taped up the back-side of the inlet with gaff tape. If you peer down the inlet, it's significantly restricted and from my eyeball I determined it's smaller than the TB inlet tube. I opened up the drivers side with an oscillator tool. I also removed the leaf guard, but it really doesn't appear restrictive. I have heard someone mention the term "turbulence" in reference to the leaf guard, but I doubt the turbulence reduced is enough to notice. When you consider the temperature increase developed by the compressor at the intake manifold, perhaps the tape does no good either.

But wait a minute: There is a very noticeable improvement in engine happiness! My right foot is happier! I grin more!

Your happiness may vary.

Looks like the 2018 GTIs have vertical slots cut out on either side of the grille. If you're going to cut open the blocked holes on the air intake duct, wouldn't you also need those vertical slots to help the air get up in there?



I'm sure a replacement grille just for these slots would be prohibitively expensive but there are some intake manufacturers that provide a template to cut a neat looking scoop into the driver's side section of the grille. Like this one:



I'm sure it wouldn't be too hard to 3D print something like this...

EDIT: just found this thread:

Interesting. I wonder if the '18s have the duct open on both sides then? I'm also curious what the cost of that piece of the grill would be.

I think the forum member breaking badly confirmed that the holes for the air duct are still blocked on the '18s despite the changes to the grille.

Why is that part sold in other countries? Why doesn't the American Golf have that piece?

I think this is it at about $210.00.

https://vwpartsdepartment.com/parts/...iagram=9282017

I'm wondering if it would fit the previous MK7 models.

does anyone just sale the front with Dual inlet open that works with the stock intake?
Just like the Racingline R600 Cold Air Intake?

You don't need to buy one. Just get a Dremel and drill out the inlet on your stock intake. If you really want to buy one ECS sells a carbon fiber one

I've done a lot of experimental stuff with this and viewing under the hood of the new mk7.5s, I literally think they just made a mistake. I think they realized that it was blocked and did some testing and saw that a vacuum could pull air from the other side but that obviously this is not ideal..

They probably pitched it as "more weather proof." And we're so far gone the rabbit hole they just decided to leave it.

That piece is not used on US spec VW to avoid a snow packed inlet, which is one of the myriad development tests the vehicles undergo. It snaps in/out which is too much to ask the lowest common denominator US driver to perform in the event of a packed inlet.

There is provision for a screw to secure it in place, too.
