Uni oiled foam pre-filter

Looks almost factory 
. Forgot to mention, if you still see any fine dust/dirt in the intake tube post filter after you clean it up, you may have to use some grease at all the joints to seal things up. Had to do that on the silicone hose of the Racingline R600 box I had on my old GTI.

Uni and bel-ray both have foam filter oil
Yes I oiled it with the Uni oil. Very tacky.
Fab1 is what's needed
I use the Uni oil. Hard to go wrong with the oil made for the filter...
The uni oil evaporates pretty fast leaving the filter dry. The fab1 oil stays.
Uni filters do a pretty good job of dust removal because there’s no single path for air to take through the filter. So any dust particles end up flung against the tacky oiled surface.
They are perfect for pre-filters for an otherwise underperforming filter (i.e. K&N).
UNI actually tests their filters in high dust environments like Baja. While my dislike of oiled gauze filters is well-documented here, oiled foam is NOT the same- it has much better filtration.
The downside to oiled foam is that it needs frequent service to maintain its performance. If left in place too long, they get really restrictive really fast.
In a pinch, chainsaw bar and chain oil makes excellent foam filter oil.

Glad it seemed to work out for ya! I'm interested in what your Si numbers will be on next UOA too.
I used the Amsoil foam spray and cleaner on my Monsterflow Foam Filter, Weapon-R and ive been looking https://ramairusa.com/ but my AEM is staying the course so it's hard to wanna buy another filter.
What can you contribute towards establishing a maintenance/oiling/cleaning routine for someone like TiGeo or myself, trying to get extremely high quality filtering while deviating from the factory intake setup?
