    Hey guys. I've always been partial to K&N but I see a lot of talk of aFE on here. I've never used or purchase aFE. What is the general consensus on this?? :confused:

    Drop in filters or CAI? I've had a KN drop in since I first got my truck, no probs yet.

    In terms of a drop-in filter, oiled vs oiled, zero difference. AFE does offer the dry filter that does not use oil, thus easier maintenance. Also some debate on the oil fouling sensors, but that tends to be more operator error by over-oiling it after a cleaning. Green offers their oiled filter that has a small production difference giving it a larger filter area when compared to the other brands.

    CAI kits will vary by general design. K&N is nearly all open element style, where AFE is open element as well, but has enclosed units available for some applications.

    I bought an afe a few months back and it didn't bolt up right, one of the holes for the filter surrounding area wasn't even close. Turned me off of afe, next one will probly be k&n. And the filter is loud as hell and rattles in the engine compartment.

    I have had multiple K&N products and the fit and finish was perfect...I don't care much for oiling the filter so if I decide to get an intake for the Taco (for sound ONLY, just like on my other vehicles) I will give aFe a shot...

    I don't expect power or higher mpg. Just a one time purchase for a drop in that I can clean every 3-5000 miles. I haven't even had my truck for a yr yet and I already have 20,000 and plan on driving to florida next week. I can't afford to repeatedly buy filters haha. So a drop in for mostly convinience.

    Whats the deal with this secondary coal filter that people are removing?

    I just removed mine, http://www.tacomaworld.com/forum/pe...ary-air-filter-diy-another-way-1gr-fe-v6.html but I have not noticed any difference yet. And Chris 4x4, along with others agree that removing it gives you no benefit.

    Go with whatever is cheaper.

    People only prefer Afe because they are retarded and don't understand how to properly oil a filter :p.... lol j/k

    K&N's have about the worst filtering of any filters I have tested. If you live in a dusty area, you couldnt pay me to run one.

    OEM. Then.....as much as I hate to say this, Fram. From there, AFE dry, AirAid 7 layer Gauze, AirAid 5 layer gauze, and the TRD, K&N, and 2 other oiled gauze filters tied for the worst, as the dirt levels in the oil were off the charts. The 5 layer gauze from Airaid maxed the levels of silica, but not higher, the 7 layer one was about 100 ppm from the max. The OEM filter showed no silica in the oil, where as the Fram had only a trace. The AFE dry was about 2/3 up the scale, so its not "good" in a dusty environment either.

    WIX was right there with OEM. No silica in the oil.

    The factor interval for the air cleaner is 30,000. It simply isn't of any significant benefit to replace sooner, and dirty filters actually work better at trapping dirt.

    Does this apply to the cold air intakes too? Or are you specifically referring to drop in filters?

    Exactly right. Anyone who doesn't believe that K&Ns have lousy filtering needs to do some testing of their own.

    The limited "Cold Air" intakes I have tried have given similar results. Interesting enough, the Airaid intake had more silica in the oil than their drop in filter allowed. I couldnt test the silica levels of an intake with a OEM style filter, as none were avalible.
