Small filter in the air filter box - what is the purpose?

[Knudsen]

Hi, I am changing the air filter to a BMC and doing the cold air intake thing at the same time.

What I have discovered is this small filter in the bottom of the filter box (see picture) and I am wondering what the purpose of it is?

And also it might be small, but I guess not to small to not suck in hot air from the engine compartment?

Best regards

I believe this to limit water and other debris from getting in the box..

Well it might be, but at the lowest point of the box, there is a hole which i guess is a draining hole. The filter is placed about 1/2 inch higher than that......

I think it's if someone shot a load of water thru

your air filter.

Hmmm, well yes it could be doing the car wash etc. :oops:

Maybe a monsoon that dumps about 5"inches per hour.

Yep

By the way it's a funny box - I saw in another forum a question about a sponge in the box, at the same place as the draining hole. My box did not have that, but as far I can see there are holes for it. Maybe the sponge is for sucking up the monsoon...... ;)
