yep good filters, MAF friendly as not oily. Can improve turbo spool up time a bit and makes a bit of a gruffer noise.
Green filters are very lightly oiled, its the oil which catches the fine dust..
REALITY CHECK for those who dont know any better..
Oil contamination on MAF's is 90%+ because of the engines own oil breather system venting back into the turbo intake pipe, along side the dump valve which puffs excess boost about on and off, which blows the oily mist onto MAF's.
Only in extreme circumstances so induction kit coated/oiled filters actually cause this oily coating, and when this does happen, its user error during cleaning and re-oiling or re-coating, putting on way too much to saturate the filter.. It is obvious excess coatings can be sucked out of the filters.
Out of the box, Green cotton leave no resdue on MAF's

I thank you
And we have listened thank you Bill
But can I ask , I know you have posted this a few times on this and other forums , do you have a sigh every time you post up this?
I have seen a few posts like this on other forums , just hope this great one take note

Yes I did that system with a paper filter, leaving the green cotton a week to absorb what I thought might have been too much oil. TBH after that it did look like a new one maybe I am a twat!There is another alternative, which would be to buy a new filter, but sell on your old one. Obviously you'd have to ensure the buyer was aware the filter was used and needs cleaning/oiling.
Another thing you can do (which I did) is this:
Buy two filters and a re-oiling kit. You could buy the 2nd filter & the kit later if you want to save some dosh initially. When the first filter is due for a clean, take it out, drop the other one in. Assuming you dont have anything blocking the airbox (on the Fabia vRS the seat strut brace is a common mod, and that kinda gets in the way, although you can swap without taking it off) it takes 15 minutes max.
Then clean the other filter, dry it at your leasure, oil it and leave it to settle. This allows you to remove any excess easily. Once the filter is 'ready', stick it in the box in readyness for the next swap.
For me this system has worked well, no new MAF needed and I dont have to rush the job.
Worth a shot
Or you could just buy an air filter that doesn`t depend on oil to catch particles and doesn`t need to be oiled when cleaned so zero chance of any MAF damage from the airfilter. Amsoil
I am sticking with the stock paper filter and have modded the airbox to make the inlet larger and fitted a larger feed.Have you guys ever seen opened up OEM filter? Now open up any performance filter to compare. It doesn't take a genius to pick the right choice.
It's not the filter that restricts, you can log air flows with the OEM filter inside the OEM box and compare to it with no filter at all inside the OEM box...
If you want cheap performance filter, just use pantyhose from your girlfriend/wife or don't use a filter at all.
Only foam type performance filters have any kind of filtration capabilities comparable to OEM filters, but they are hard to clean.
I use original filter with modified box. My van has 102hp originally and now 3,5 times that. With my ongoing build I'm going to use some big OEM filter from Ducato, Duramax, etc.
