K&N Dilemma

[Posm]

I have read all the posts on how the "K&N will not stop the dirt. " Yesterday, I switched out the K&N for the stock filter and I'm soooo disapointed. The turbo spool up is much slower and that glorious whistle is nearly gone. The seat of the pants feel is much worse, however, that could be my sinking heart aching for the turbo whine. I do not want to destroy my truck with dirt particles, but I'm not sure I can live with it the way it is now. Is all the dirt talk, just people with a vested intrest in seeing the K&N fail(Amsoil salesmen) or does anyone have any real world prblems they could trace back to the K&N filter. I may be interested in one of the Amsoil filters, however, I have had great results with the K&N in the past. Besides, I already own the K&N.

I would like to get more info on the kn filter ,how many micron as well as how many micron on the stock one,getting a tite seal is important but putting in a inaddiquate filter would be a big mistake ,I would be currious to know how you could flow more cfm thru the same micron filter without increasing its total surface area,propper air filtration is probable the single most important maintance item on our trucks,I am hessitant to switch filters as I have read too many contradictory opinions

If you really want to run the K&N, then use it and get an oil analysis done. This should prove or disprove any reports you are hearing. The analysis will inform you of any problems with the filtration system.

I have run a K&N on my truck since new. I now have 68,000 miles on it. I don't use any sealing grease and my oil analysis's have all been normal.

The K&N went in the 2nd day I owned the truck. That was 3 years ago, and I've never had a problem or a speck of dirt anywhere in the air intake.

Dito on the oil analysis ideas. I am getting ready to send in a sample now that is with the stock filter on it. Then I am going to buy a K&N, try it and get another oil sample done. If it comes back okay I will keep the K&N. I also plan to do oil samples on every change, its only $20, cheap insurance as far as I can tell.

If the K&N is installed correctly and not damaged you'll have no problem. I have 120k on mine,no dust in the tube,low silicon in oil tests.

What is the pn# for the K&N filter that fits in the stock airbox, and the PN# for the cone filter? Thanks, Tony

P. S. Don't say go to knfilters.com. They just keep saying that app is not available

Those of you who are using a K&N and doing oil anaylsis have you seen a drop in pre turbo temps?

I disliked Both... Brand K and Brand A...
for different reasons.

I had religiously used Type K's and had an oil analysis on one of my vehicles as it approached the end of its bumper to bumper,(non-Dodge Ram) and it came back w/ a higher than expected Silica Reading, on a less than 1yr old brand K filter. Out it went and in went a Wix.

A previous experience with brand A left me grumbling about perpetual filter oil drip and mess in the airbox and beneath it. I did not have oil analysis performed, I didn't keep it in service long enough because of the mess it was making. Yeah, it may have been "overoiled" as delivered, but I wrapped it in a towel and placed it between two 25lb bar bell weights to try and get the excess out... it still dripped. Again, this wasn't on my Ram, and I didn't have oil analysis performed, so I have no basis to be critical of Brand A's Filtration. I just didn't care for the mess.

There's been some hype about the AFE filters, but I don't know anyone running them, and I haven't any experience w/ their products.

Fleetguard for now.

FWIW, I've had a K&N on my 98 since day 1 (92,000 miles) without a problem. Put 70,000 miles on my 95 without a problem either. The main thing is to keep a good seal with grease around the filter.

I got the K&N as soon as the stock filter got dirty. Have had it in for almost 8k miles so far without any signs of dirt past the airbox. I put a very good seal of grease on the bottom edge of the filter before installation. Part number on the filter for stock airbox is 33-2056. I got mine from the friendly folks at Autozone, but know it is available many places. That in combination with the turbo silencer ring removal makes for a nice whine from the turbo. Has provided a good indicator of turbo boost until I can get the gauge I just received installed.

If you want a good "shadetree mechanic" method of checking how much dirt is getting by your air filter, regardless of brand try this:
Pull the intake hose off the front of the turbo and look at the leading edges of the blades. Red360 ran a K&N and spent a couple hours with a Q-tip and laquer thinner to get all the gunk off. Just something to try.

I just recently took the K&N out of mine. I just never could get comfortable with the idea of grease sealing it. Also, I was concerned that it might not stop the dirt with the extra boost I was running (30# vs stock 18#) It's been proven there's no extra horsepower from the K&N and the extra turbo sound isn't worth risking an engine that has to last me a long long time.

I put in my OE K&N when the stock filter moved the filter mizer. I ran it for approx 20K and yes I did have black build up on the turbo blades. The problem is with the OE box not the filter. Changed over to the RE-0880 and the Psycotty ducting 45K ago and the inside of the turbo and intake have been as clean as a wistle ever since.

I had a good buddy that have never used nothing but Dc filter and his turbo was bad, after much searching we found his A/F box was worped on the exhaust manifold side.

As far as the AmsOil filter goes the foam construction should help seal up the bad OE air filter box.

FYI I have been getting in excess of 32 PSI since I installed the RE-0880 and the Psycotty.

The RE-0880 filter and the Psycotty drop EGT 150-175 deg towing.

Had my K&N on for over 10K miles now. Checked the turbo blades last night... no buildup of any kind whatsoever. When looking in the bottom portion of the air box I noticed a light covering of dust (not normal in the pacific NW rain forest, ha!), blew it out with compressed air and found the entry tube wasn't securely inserted into the fender well area. I can only assume the front tire was picking up some trash. I will examine the filter again upon the oil change to see what the bottom of the box looks like after hooking up the inlet tube.

I have heard that some trucks with stock filters had a black residue on the turbo.

Fellers,I just got an e-mail back from K&N filters and Don told me that all of their filters are good down to 1 micron,I am satisfied with this preformance and will be going to K&N soon,Like many have said the seal is the most important thing,a little thick grease and vwoila #ad
