Anybody have any suggestion on the best air filter for dusty environment where the dust is fine! I don't mind oil air filters but i'd prefer a dry one.
Ooh..k. not sure what specifically concerns you, you mentioned "fine" dust.... most dust is.
A good quality OE filter is still the defense that the Engineers specified. Jeep Engineers certainly account for long protracted exposure to extreme environments (incl dust) the key is not a different filter. It is frequency of replacement.
Want to add a layer of f protection "if" warranty isn't a concern - add a pre-filter paper to the OE filter and enjoy the ride.
Dusty environments will require more frequent air filter changes. The more restrictive the air filter, the less air flow into the engine.
I'd stick with OEM, and change more often.
IMHO, anything more than that is just unnecessary concern.
A dry filter is better at filtering than a filter you apply oil to. [Hide] Just look at used oil analysis of an engine using an OE filter vs. a K&N and you'll see what I mean. An OE filter is a good place to start. Donaldson makes a good filter as well.
In a dusty region I would only use a dry filter. The extra couple of HP a K&N type filter offers is not worth the additional engine wear. Opinions vary.
IMO stick with the OEM air filter rather than any of the parts store brands. There is a difference in media quality, density, fit/finish and overall construction. Pre filter protection makes sense if your expecting jeeping activity in high dusty areas. Some jeepers like the pre filtering + cool air capabilities in a snorkel kit even if your not truly snorkeling
pre-filtering would collect dirt in the filter box!!! but i think i would consider replacing the oem filters more often. have you had any experience with the 7 layer pre oiled aFe filters??
