White foam on factory air filter

[rickety]

If you have a snorkel fitted there is no need to have the foam pre filter because you are drawing in cleaner air than original air intake . I have also noted impoved fuel economy without the pre filter.

I have spent 30mins searching the forum but can't find the answer I'm looking for,

I stopped in and bought a Factory filter today for the ML 2009 3.2TD GLXR and when I went to install I noticed the old one did not have the big white foam sheet under it.

Is the white foam piece meant to be removed or is it a kind of pre filter, The old one did not have it but had the little tabs where it would have attached.

Part numbers are identical.

Anyone ponit me the right way

Thanks

Where you pull that idea from?

Does a snorkel reach into a new atmosphere or something?

What a load.

Following a car in convoy, to closely, on a dirt road and you are sucking in the worst case of dust ever.

Snorkels dont make that big of a difference. You have been reading to many marketing brouchers I'm afraid

Has anyone recorded the noise from the snorkle? Link? I know mine whistles a fair bit with the stock filter in but how loud can it really get?

Heavy breathing asthmatic on steroids.
