Ram air vs centrifical prefilter

[gnel]

I had both on my JK. The ram air, facing forward, did exactly what you'd think it'd do. Rammed a bunch of dirt and bugs into the airfilter. I switched to the "mushroom head" with the internal fan, worked fantastic. Kept the filter MUCH cleaner.

I still have the head, fits a 4" snorkel, if anyone wants it...

Thanks for your info and the offer. Mines 3.5 so the 4 inch won´t work. Cheers.
