Why a K&N filter?

[brobeson]

I see a lot of posts about the K&N filter. I am getting a new 3500, HO.

If I put the K&N on the truck, does that effect any part of any warranty?

Why do so many people use the K&N?

Whats the low down on K&N? The good, bad and Ugly?

Have you used one and would you use one again. Did you go back to a stock paper filter?

Thanks

Bob

go one better and order the amsoil TS106

very high quality filter and no it won't void your warranty.

more air= lower egt's #ad

You dont want a K&N go with the Amsoil filter,a much better filter,reuseable also.

K&N Filters will not void your warranty (My dealer here even sells them). What they will do is outflow a stock paper filter by more then 50%. If you drive in extremely dusty conditions you might want to avoid them though as they can let fine particles through. The RE-0880 filter is a cone style that replaces the factory airbox and flows like crazy. But order a 25-0880 foam wrap around Pre-filter for the cone filter. That will stop all the dirt and wont hurt the airflow. With the filter and the foam sock, you will be flowng about 70% more then the stock paper filter/airbox setup and getting almost the same filtration. If you want to keep the stock airbox, you should go with the Amsoil. It has a foam pad in it that stops more dust then K&N's stock replacement. To get the K&N stuff, the cheapest i have found is www.summitracing.com or call them at 1-800-230-3030 and just use the K&N part nunbers i listed above. As far as Amsoil, there are alot of dealers. I use "CPFF" another TDR member. It basically breaks down like this;
Paper= lowest airflow but best filtration
K&N= Most airflow but least filtration (Unless you are suing the foam Pre-filter with the filter)
Amsoil= about in the middle but they only make a stock replacement, you dont have an option for the larger cone style filter.
I do all highway miles and never go off road. So i have just the cone style K&N. Every oil change i wipe down the inside of the Rubber turbo inlet with a white cloth and it still comes out clean so i am not worried. But if you are in real bad conditions you NEED the Foam pre-filter. Everybody has a different opion it seems on this matter so you will hear all different ideas. Go with what works for your driving conditions. And change you oil Regulary. That is the second defense against dirt being sucked into the engine.

Hey Bob,you really have to check out the psychotty box,the only problem is some guys don't like to drill holes in there trucks but imo its no big deal the sound that comes thru the firewall is really what we want to hear since we bought turbo diesels honestly check it out. Good luck JdmJoe

 

[EMDDIESEL]

He is right, the Psychotty industion is a nice idea. You will have to drill a 4. 5 inch hole in the firewall, but it is real easy. The system uses the K&N RE-0880 filter and will draw cooler air from the windshield cowling. A definate improvemet over stock, but it will be noisy. So if you like the sound of the turbo, go for it.

wiil and joe
thats a definite go for me
i want that whistle more the better, as far noise i love that diesel running

Dont forget to ditch the silencer ring too!

i saw a 9 hp difference between the stock factory filter in the stock airbox , when i propped open the cover with no filter but with the stock inlet hose on the turbo still it jumped up the 9 hp , but was still down a couple compared to earlier when i had a k+n re 0880 on it . the stock filter and housing is really restrictive .

I put a K&N in mine about a week ago and it helps out a little, you can tell, plus you can really hear the turbo sing to ya, i would get rid of that stock muffler to, that helps out a lot.

Dee Rawson and I tried his 0880 on Heberram's ETH while dynoing at Edge, a few months back. There was absolutly no power increase over the stock air box that we could see.

 

[EMDDIESEL]

You wont see an increase on a dyno. The increase is mainly in acceleration. But there is no denying your truck will be quicker. Go to a long stretch of road or parking lot and time with a stopwatch the acceleration with the stock setup, and then the K&N. There is a difference.

I have the re-0880 and 25-0880 pre filter. It is also strait piped and there is a definate improvement in spool-up of the turbo.

thats news to me Bart and EMD , i was down on power from a run earlier in the day , we couldn't figure out why ( ted j. was standing right there , guess its like the change to 4" exhaust doesn't increase HP a bit either #ad
, opened up the airbox and it came back up.

had a larger increase with the edge on a lower setting , what filter in the stock airbox were you comparing it to ?

Bart is correct on the Egde Dyno HeberRam's truck wasn't giving Steve the numbers he wanted and I pull my RE-0880 out of the Psycotty housing and we did it up on Steve's truck and made two or three runs. I think Steve already had a OE K&N in the stock housing already. The most we saw was 1 or 2 HP but it wasn't repeatable. To me what the the RE-0880 and Psycotty does is allow me to pump in more fuel and keep the EGTs in check (Kinda)

TDR issue 25, page 40, "Technical Topics" by Joe Donnelly states:"If the air filter is oiled cloth, the oil plus road dirt will eventually coat the intake piping and the intercooler, reducing the efficiency of the intercooler. "

So even if the K&N has the foam pre-filter to handle the dust, aren't we still at risk of sucking the oil into the intercooler? Doesn't the Amsoil filter system use oil too?

I'm giving serious consideration to replacing mine with the stock filter.

Took my k&n out and went back to paper. I change it right away if the filter minder moves a hair. The way I see it if your not moving that minder your passing all the air the diesel needs. The k&n was passing way to much crap for my liking. I didn't see any difference in egt or sop hp.

Hey guys RE: psychotty,I read some bad threads about the quality so I got to shop this morning popped hood and checked,I pulled it out and pop riveted seams,you must use flat washers to back up rivet,also shaved that 1/2''seam down where it goes into rubber seal,I also noticed that filter goes into small end of cone to far and is restricting to much air so I backed filter out so it is flush at the other end[large end filter and housing flush]I also drilled about [10] 1/2'' holes for more free flow I think this simple modification is going to really improve this unit,oh by the way I did install piece of metal so filter does not close off end of cone,I'm thinking that some of you might have had the same problem I did bacause when air flow is compromised you will draw real hard thru filter maybe some oil as well,just A thought.

In regards to the question about the K&N filter oil eventually coating the interior of the intercooler. If you over oil your K&N which alot of people do, it will, in time (like 2 or 3 years) leave some oil residue in the intercooler which can act as an insulator. But, all you have to do is something i normally do once a year anyhow and that is take the Intercooler out of the truck (Not that big a job, just a few bolts) and dump solvent through it to dissolve any oil residue. You can use Carb cleaner, just make sure you let it sit for a few hours to let the solvent evaporate, a shop blowgun helps. Your intercooler will be good as new. That is a small task for the power gain you get from the increased airflow from the K&N.
