Foam vs paper air filters..., Which is the best? Please say why? Options

[second wind]

Hello Teener World,
I have been a suspended oil foam filter fan since my motocross days (50 years ago) but just bought a brand new Mann paper air filter. My K&N is looking quite worn out and my flaps guy said why bother doing the cleaning and oil anymore? Just buy a quality new paper filter and be on your way. So I did and would love to hear what others have to say about the topic....thank you very much to all!!

I've never seen a factory installed cotton gauze filter on anything...
Ferrari, Lamborghini, Bentley all have paper filters. They are usually very large.

The K&N style filter was originally designed for off road racing where the environment could be extremely dusty, and a paper filter would become clogged much earlier.

So, unless you're in a dust bowl a paper filter is a FINER filter than a gauze.

It does a better job of filtration up to the point it clogs...

Another possible issue with the K&N style is a EFI system with a MAF sensor.

These are either in the filter housing or the intake tube to the throttle body and the oils that are in the K&N filters tend to coat the fine wire sensor and screw it up.

Check engine lights, strange running are the end result.

All you have to do is clean the MAF.
It's not hard.

But, by the third time you're ripping it out and carefully cleaning an almost invisible wire you end up putting a paper filter back in...
