Intake mods

So I was out tinkering and decided to check and see if I could improve the factory intake any. I pulled the front part of the intake apart ( that is mounted behind the grill) and add a new intake path. From what I found is that there are two intake areas where it pulls air in from behind the grill. Only one of ours is used and it's on the passenger side with a flapper assembly on it. The other side is blocked off which leads directly into our airbox. So I cut mine out and sanded it down. I hope it helps besides making more noise. I'll try and post up some pics explaining what all I did.

The left side is the intake/ flapper. The right side is sealed but has areas in which we can cut out. So I drilled some holes in the corners so I knew where to cut.

Here is a few pics on how it turned out. It is now a straight shot from the grill into the airbox. I will run some un scientific tests to see how well it does lol. Mostly I'm looking at intake temps but I figure this would allow for more direct flow than the previous factory setup.

Awesome DIY mod, especially with so few aftermarket options. I wonder why they would have blocked off one of the feeding paths from factory. Probably just to reduce intake noise?

It would be great to see more sophisticated air channeling which doesn't have take much work or cost to you, seen some Honda guys do it for under $50 with home depot bought material.

Plan on doing the same thing.

Couldn't believe how much they wanted for

And the above pictures don't show the flap that we have to keep the hot air out. I doubt that our 2019+ Jettas will get the same temp readings. So, I will save $330 and dremel/sawzall my inlet per the Robdee32 pictures. Just remember, the design of the inlet allows heavier rain water to fly thru while the air makes that 90 degree turn. If you mod this inlet, avoid flood zones.

Just received my AFE Pro 5r free flowing air filter.

For those that want a tube/pod setup.

And, I already removed the rodent blocker under the air filter.
