is yours definitely not oiled?
i was going from an airbox, so for me it was LOUD! not indiction roar, infact none, just sucking and whistling from the turbo then mega loud dumps, and i use an OE 710N!
The main benefit of these filters is that they are cheap, and being paper they filter better than foam or that cotton stuff k&n use.
They are slightly oiled, it comes in a plastic bag and you can see the smearing of the oil on the bag and also on the plastic, yeah going from a silent airbox to this will sound louder
As for filtering better, you'd have some convincing to do there, by the time you add the silicone adapter and the filter you're into the cost of a heat shield and cone setup which I would say for those looking to go down this route go for instead, you ideally need the heat shield with this setup too so you're looking at a kit cost of:-
£20 for silicone pipe
£20 for heatshield
£13.50 for filter (needs replacing at each service)
as opposed to:-
£20 heatshield
£15 for cone that fits onto MAF off ebay (non oiled one) can be washed and re used
This may be up for sale soon lmao
