gearhead 03-09-2005, 10:55 PM K & N advertises their filter will not void the warranty. Why specifically do the members do not recommend this air filter? most will say that it lets to much didt thru JhnZ71 03-09-2005, 10:58 PM I have their Gen II FIPK intake on my truck, and on my 1999 silverado, and on my 2002 Jeep Grand Cherokee V8, I have K&N filters in both my 03' Yamaha Grizzly 660, and my 04' Kodiak 450. I have never had one problem with K&N filters, they filter well enough for my cars. I run my atvs in the dustyest nastyest enviornments i can find and still no problems, alot of my friends run these filters in their daily drivers as well as their off road cars. When I take my truck off road or to a particularly dusty place i just slip on the prcharger onto my intake and have no problems. You can literally go 50k without cleaning your K&N and have no problems with it. I wouldnt bother with Foam or anything else, just get a K&N they work fine unless you drive your truck in extreme conditions, you can get the K&N filter at Autozone and even the FIPK at autozone as well, if you want you can order the prefilter from them as well. bigblackdmax 03-09-2005, 11:34 PM I just had my computer reflashed on my truck and a code kept coming up for them that was for the mass air flow sensor. They tried to tell me that the aftermarket oily filter can get oil on the mass air flow sensor and mess it up. They did replace it under warranty this time but said that they wouldn't do it again because of the oily filter. Just something to keep in mind when oiling your filter.

Read this http://www.dieselplace.com/forum/showthread.php?t=18976 and all will be made clear. :thumb: Or, if you've got a lot of time ):h, this is the grandaddy of all Air Filter threads. http://www.dieselplace.com/forum/showthread.php?t=10372 Salmonbum 03-10-2005, 06:36 AM Over-oiling is the reason for throwing a code for the MAF sensor. I'm guessing most people run out and get the recharge kit with the aresol can and spray away, not keeping track how much they use. The K & N fliter for the Dmax needs 3.38 oz of oil and that is it. I re-charged mine with the squeeze bottle and took my time, measuring out exactally how much oil to use. No problems. It's almost impossible to measure the amount from the aresol can, making over oiling very easy. EppmanZ06 03-10-2005, 02:37 PM Yea, I had a stealer try to tell me that my K&N filter was why my engine was throwing codes, I tell him he's full of it and I check the code the computer was throwing, it was a low fuel rail pressure code, so I change the fuel filter and everything's fine...They're looking for excuses all over the place not to do any work. And if you think oil may be a problem, carry a can of contact cleaner in the back seat just in case... Terrain Twister 03-10-2005, 03:11 PM Contact cleaner sounds great,BUT you better make sure it has completely evaporated before starting that thing. Otherwise, Oil in the itake will be the least of your problems!:eek: HD-Nate 03-10-2005, 03:25 PM You can get away from the over oiling problems by taking a couple small precautions. When I buy a K&N filter, I always buy 2. While running one, I will clean the other, oil it down and seal it in a plastic bag. By the time its time to change the old one out. All the excess oil has dripped off the newly cleaned filter and is ready to go. You can buy 2 or save you old paper filter. Put your paper filter in place for about 1 week while you newly cleaned K&N is dripping off any excess in a plastic grocery sack. I have run K&N filters on all my cars/trucks for almost 20 years now. All my vehicles go well over 150k miles with no K&N related problems. I wipe out the area behind (box/tubes) the filters every spring and have never found any dirt. EppmanZ06 03-10-2005, 03:35 PM Something I remember reading somewhere is that our MAF sensor enters a self-cleaning cycle whenever you shut the engine off. Basically, it hits the NiChrome wires with a good shot of voltage to burn off anything that may have gotten on them during operation. And I would assume that the filter oil, as flammable as it is, would more than likely burn off as well... Tsckey 03-10-2005, 05:15 PM The knock on K&N and other high flow gauze or foam filters is that they are better at flowing than filtering. SPICER's invaluable contribution to the quest for knowledge has convinced a lot of us that in addition to increasing airflow, these filters also demonstrate that you can sell almost anything with the right marketing campaign. Many people relate that they've never had a problem with the filter. One would expect no less, but it is the slow damage done to the engine by letting in too much dirt that is the harm to be guarded against. If those using k&Ns or other gauze filters are running in dirty environments AND getting good results from UOA, then by all means keep going. But absent the oil analysis numbers it's not possible to tell whether one is having no problem with the filter.

I'm running the CAI with the K & N cone filter!! Grey Ghost 03-10-2005, 09:19 PM So, Besides the fact that they can't keep the dirt out!!
