Do you find yourself leading a pack or driving behind a bunch of people?
If you don't have a snorkel, it's time to get one, if you have one, it's time to get an enginair 4-150/465 centrifugal pre-filter.
Fram filters, btw, are not as good in terms of filtration for both air intake and oil vs oem. I'd just stick w/ Toyota paper 90915-YZZD3 (more capacity over YZZD1) or 90915-20004 if you can even find them (Toyota 2JZGTE Supra Filter w/ Foam Depth Media).
But yeah, good call on the uni filter mod, I need to do that too since I'm always offroad. I just wish they routed the air pump intake into the cabin instead. Easiest way to get filtered air.
