K&N doesn't stop dirt!!!

[Archive]

I have about 6000 miles with the PSA and about 10000 with the the filter. I take it off every time the oil is changed for ease of filter removal. I haven't seen any buildup of dust on the turbo fins at all.

Vaughn, could you be over-tightening the clamp on the filter itself? I changed the hose clamp I use because when it was full tightened, it would still leave a gap. I would love to find a large enough spring style clamp. Ty to use them on most everything when I can.

well i did some routine maintenance on my real truck this morning... after reading about the K&N oil and dust problem i decided to check mine... . i installed the K&N about a month ago and have about 1500 miles on it including a vacation trip to the mountains... much to my disappointment there was oil all over the turbo vanes and on the bottom side of the turbo hose... this was a stock K&N right out of the box... . there was also dirt in the oil... well the K&N in mine is OUT and the fleetguard paper back IN... the only source of the oil had to be the filter and the prior owner did not use the K&N so it is obvious to me where it came from... . sorry K&N guys

Back to over oiled,you don't need to soak down a K&N like you do a foam lawnmower air filter. Dustoff,maybe yours was over oiled from the factory,clean it and try again. I've used K&N for ten years,wouldn't use anything else. Sure the stock filter does it's job-just look at your filter minder compared to a K&N,I know what I prefer for max airflow and HP. My $. 02

Even if it where over-oiled, dirt being on the coating inside the tube should not be occurring. I have the stock filter set-up with almost 5000 miles on my truck and live on a 1/2 mile very dusty road which I usually travel several times a day. I wiped a cloth inside my tube yesterday and it was very clean. I had the stock set-up on my 97 as well and never had any signs of ineffectiveness. I realize the resulting oil in the tube may trap more dust, but the rubber on the inside is very tacky and would catch some if a significant amount were passing through the stock filter.

hey you dirty-tubers!! you are doing the thing that Scott1 discovered, right? that thing being: shore-up the innerbore of the filter outlet w/ a 1" long piece of 4" exhaust tubing to prevent distortion of the rubber pieces--just asking,since there's such a disparity between so many peoples' results... mine is clean, even with a factory-oiled (overoiled!?!) filter and 25+lb peak boost--rm

I drive on a dusty road for about a mile 3 to 4 times a week. So dusty that when I stop, I sit in the truck for about 15 seconds to let the dust settle down before I get out to open the gate on that road. I have had the K&N RE0880 cone filter on for over a month, and the Psycotty housing on for 2 1/2 weeks. Pulled the turbo hose off the check it and it was absolutely clean. No oily residue or dust. My boost gets as high as 32psi. Don't know why some are having problems and others are not with the same filter. Just reporting my results.

I use to run the K&N filter, then I checked out the Amsoil filter and watched the video that compared the K&N and Amsoil head to head. After watching the video I purchased the Amsoil filter on the very next payday. I switched since the Amsoil filter had better filtration efficiency over the K&N. The amsoil filter is also a high flow filter like the K&N and I still get that nice turbo whistle and air swoosh sound when accelerating or shifting through the gears like with the K&N. I don't have to apply sealing grease to the airbox top like with the K&N. To K&N's defense their filter is easier to clean and oil than the amsoil filter in my opinion. I cleaned my Amsoil filter for the first time a few weeks ago and it was a hastle, used lots of dish saop and simple green to get all the oil out. Also was a bear to apply the oil and get it worked in evenly throughout the filter. One nice thing with the amsoil filter is it only took a few hours to dry after cleaning, the K&N had to sit overnight in my experience. Besides being a little more difficult to maintenance, the amsoil filter does tend to "leak" oil into the air tube to the turbo and also in the airbox, which then drips out the drian hole and onto the inner fender if over oiled. The Amsoil filter was over-oiled out of the box and pulled my filter-minder almost to the red, had to take a rag and dab some of the oil out of the filter and had some drip out of the airbox drain hole all over the inner fender far awhile. I feel these are small sacrifices for what I view as a better flter between the two.
From the info I've seen from Amsoil, high quality paper filter have excellent dirt removal abilities like the amsoil filter, but lack air flow ability like the Amsoil and K&N filters.

If you read the K&N warranty for what it says, they warranty the filter only. If it fails and allows dirt into your engine, they'll replace the filter only. The literature about the MF ruling is a smoke screen as DC isn't going to warranty engine damage caused by a faulty aftermarket filter and K&N has said in writing on the box that they only warranty "the filter" if it fails. Any engine damage caused by the filter is yours to pay for. It's in writing on the box. Although written very carefully and deceptively by their legal dept. If an engine fails due to a faulty oil pump, then of course DC can't deny warranty coverage because of the K&N filter unless they can prove that the K&N caused the oil pump to go. Even then, K&N has stated in writing on the box that they only warranty the filter, not any damage caused by the filter. Even the lowly Fram filter manufacturer states in wrinting that they will cover any damage caused by their product. K&N states in writing that they will not.
NASCAR used to use oil bath filters until they discovered that some engine failures were due to tiny clumps of dirt held together by filter oil would break away from the filter and get sucked into the engine. Now they use throw away paper filters.
I'll be installing an OE K&N next time mine needs one and see how it does with my application. Alot of driving in the rain here in central Florida. If it lets anything through, lesson learned. but I like to hear the turbo sing! #ad

Vaughn,
For your answer concerning your comment, "You would think if Amsoil was really big in this business, they would have a filter replacement for virtually verything. "

Amsoil will make any size filter you wish. Just fill out a form, send it in and it will be made to your specifications. You will be stuck with it however, if it does not fit the application you desired.

I had the same problem with k&n in the stock box. I got a Fleetguard AF942M and made a round collar to fit the turbo hose. The filter measures 12"Lx10. 5"dia. . The stock filter pulled 16"wc. ,the k&n pulled 11"wc. and the AF942M pulls 2" wc. and the hose is always clean and I don't screw around with any oil.

It sounds like your idea is the best of both worlds. Increased air flow and no oil to mess with. What does the "wc" stand for and how do you have the filter mounted?

Thanks in advance.

Turbo crowd: I see from reading this thread that there are guys who still like the K&N filter. Now's your chance to pick up a spare for less than half price. I never had any problems with the K&N, but I have one for the stock airbox out of a '96. 10K miles on it. First 25 bucks gets it. Go for it!

Thanks for all this input everyone #ad


I think I am going to give the new one a chance when it comes in, but if there is any indication if dust buildup at all, it's outa there for sure!! Next try will be an Amsoil filter.

rich m, I have a 1" section of a 4" exhaust pipe for clamping support. I use a minute coating of vaseline on the contact surfaces, and when I pull it apart, there is no trace whatsoever of dirt around the seal area. On either side of the contact areas there is plenty of dirt.

I also have the large foam prefilter, doesn't have any affect on dust reduction, even pre-oiled.

Thanks also for the little tidbit about warranty issues--good thing to know #ad

That's odd Vaughn. #ad
I had my K&N pre-filter (#25-0880) on from the day I installed my #RE-0880 cone filter and noticed a marked color change in about one month from all the dirt attached to the pre-filter. I still believe you need to really soak down the pre-filter with oil, working it in by hand, letting it sit for a while, blotting up the excess prior to installation. The filter element itself is another story; just a light, to light/moderate spraying of the filtering oil is all you want.

You would not believe ALL the dirt and foreign material that washed off the pre-filter when I cleaned it! On the other hand, the cone filter was still the SAME pink color as when I purchased it.

BTW Cocahoe, wc = water column... a unit of measurement to determine suction intensity.

Well, If Amsoil will make a custom filter I would like to know when and where bacause the last e-mail I got was one line...

"Subject: RE: Technical Service Contact Form
Date: Mon, 31 Jul 2000 14:20:20 -0500
From: "Wallace, Darryn" <dwallace@Amsoil.com>
To: "'scott@toys-4u.com'" <scott@toys-4u.com>

AMSOIL can not produce or supply an equivalent air filter to fit this air
filter housing in place of the K&N RE1880. "


So, if they will custom build them, why did I get this reply?

EH?

Cocahoe,the filter has a solid cap on one end and the other end is open. I drilled a 3/8" hole in the center of the solid end and put a piece of 3/8" allthread with nuts and washers on both sides of the cap - it sticks out about 3" beyond the end of the filter. I made a 4 3/16" round collar to glue on the open end for the turbo hose. Then I used 1/8"x1" flatstock to make a forked bracket to bolt in the corner just in from the right hood hinge to accept the allthread and two more nuts to tighten down in the fork. Also made a bracket that bolts to the fender well behind the battery for the front end of the filter to rest on. With the hose on the front and the allthread on the back,it stays put really well. When I change the element,I peel the collar off with a putty knife and caulk it to the new one. The AF942M is a longlife filter(more media and less restriction that standard)element,that's why I use that one. Also because it's the biggest one that will fit behind the battery. It's 98. 5% initial efficiency and over 99% at changeout. Craig

Just checked my turbo input hose. Gave it the white glove test - no dust, no filter oil residue.

K & N stock replacement filter. Has been installed 3,600 miles. Doing the job.

Thanks for making me check it though. These kind of things are what makes the TDR a great place to learn things.

John,

My prefilter is very brown, thanks to driving in a dust storm just before yanking my K&N. I will try your method though once the new filter comes back. This may help with the problem. Rob sprayed a little on it before he handed it to me but it is fairly dry.

<font color = red> C Schomer--sounds like you found a great filter. Very low resistance, filters great, and no oiling. Now for the real question--how expensive is it, and how long do you think it will last? I assume it's not recleanable. </font color = red>

I am anxious to resolve the air filter issue once and for all. I just took a 600 mile road trip today and boy, the stock air filter really takes the edge off my horsepower!!! #ad

. The snappy responsiveness on the highway has diminished noticeably and EGTs went up at least 50F even though I'm pulling outside with the stock setup.
