What is the best filtering air filter for my 01 zx2 escort? It currently has a wix paper but if there is another filter that filters finer dust, i'd like to run that. I'm looking for the filter with the highest efficient rating@ the lower micron rating.
Thanks
Dusty
 
Can't say for certain, but Id consider an oiled foam prefilter (like K&N sells to put over their filters in dusty locations) over top of a standard OE type filter. I personally like the "fluffy" type filters like are used in toyotas and some other vehicles, as I feel they offer a more tortuous path to move through.

IMO the foam prefilter is ideal as it is easily cleaned and will catch a lot of stuff, yet it is not an oiled gauze that will leach onto the MAF and other parts. It seems to me that this is the approach for lawn service equipment and other highly dusty environment systems.
 
the oiled paper types seem to have really high efficiency ratings. Purolator makes a pure one air filter and Fram has a tough guard air filter. A foam or fiber pre-filter over a paper filter is probably very good also. my dodge ram come with one from the factory.
 
Where could I get one? I looked at Oriellys and AZ with no luck. I'd love to have one. What do I ask for? My filters don't last 10k miles before the pleats are PACKED with dust and I want an extra layer to keep the dust out of the motor. I don't care about replacing filters, just want the BEST possible protection. YES, I do run a beed of grease where the filter seals in the air box as well as the intake tube joints.

My cheapo prefilter is two layers of discard pantyhose catches good amount of leaves, bugs, sand, dust ... I removed the pantyhose from the filter every few months to clean it and put it back on. The air filter looks almost new after 2 years/25k miles.
 
OK, you worry about caking with dust...

Please realize that the filter media does very little of the filtering. It is the particle "cake" that does the filtration. That layer of dirt isnt a bad thing unless the pressure drop across is causing the engine to do excessive work.

Different companies sell a little gauge that can be used to determine the pressure drop on the filter and show when it is time to replace. If you are in that dusty of an environment, Id recommend getting one of these - it is a good investment, IMO.
 
Last time I saw a comparison of a bunch of filters, it was an ACDelco paper filter that filtered the best. The various oiled re-usable filters let the most dirt through...enough that I'd never consider using one on any of my vehicles.
 
I see no need to change what you are currently doing , Wix makes a high quality filter and just because it is dirty does not mean it has reached the end of its life. In actuality the "dirtier" it gets is when it is actually filtering the most from getting into the motor.Id say stick with what your doing , Ive never had a problem using a quality Wix air or oil filter.

This is true. Just use an OEM or paper filter of your choice don't change too soon, don't vacuum, air blow, shake 'em, Just leave it tightly in place and let it be for the recommended mileage. I use them longer because I live in a less dusty environment.

Good move. I used that routine on an old VW I ran around the unpaved roads in Peru for several years. John--Las Vegas.

No cake for me, thank you.
 
There is nothing wrong with the OEM filter only down side is they have to be thrown away every 15k.
IMO OEM, AFE pro dry and the AEM air filters are the best filters on the market for keeping the air to the engine cleanest.

That's a question for psychology class.
 
The best looking AF for my Honda is the OEM Honda AF. $30 at the Honda dealer. Change it more often if you are concerned re dust/dirt. I change every 2 years at about 18,000.
 
Best filtering is probably the OE filter. Best flowing is no filter. Everything else is between OE and no!

You are limited to what is available for your vehicle.
Check the online stores like autozone, oreily's, rockauto, advanceaduto.....

What you should consider is a sock or bag type air-prefilter. Find the tube that feeds the air filter, and add one of those store brand washable cone filters. You might have to rig it up with some plumbing from lowesdepot. This way, your OE filter will last longer, and every 10k you wash, re-oil, and reuse the pre-filter.
