K & N re-0880 filters

[csutton7]

for some reason when I try to do a search I get shutdown, so now I'll ask a question which has most likely been beaten up more than the Quarry bros in the 60's & 70's--sorry if it's old news but I'd need info--Ok-I've got the psyscotty-it's not installed-I've got the K & N re-0880 w/ the foam pre-filter 25-0880 and I've ordered the sock. So, I removed the stock air box and I put the re-0880 on and went for a test drive-cool sound. Is this set up OK? I've put the foam pre filter on and will do a test drive later--is this a better set up than just the re-0880? When I get the sock should I put it over the foam pre filter or should the foam pre filter be removed and sock over the re-0880? Or do I put the scotty in? does anyone have an idea what the diff in sound would be between just these setups & the scotty? Not much off road stuff, but it does happen now & then---thanks for your replies--chris

Chris,the foam prefilter won't fit inside the Physcotty,I'm not sure about the sock.
The Physcotty will be louder at high boost,but not so that you can't carry on a normal conversation with a passenger. You will get used to the sound fast and love it. I disconnected my Psyscotty this winter when it was real cold because I thought the intake air might be too cold,not the case according to my intake temp gauge,but I really missed the sound while it was gone.

Illflem--yea you're right the foam pre filter won't go in the psyscotty!!-chris

Chris... .

I have the RE-0880 and the 25-0880. The 25-0880 is supposed to restrict air-flow by approx. 2% as opposed to the sock which is approx. 10%. I don't think you'd ever put the sock over the 25'r unless you were running the Baha.

A K&N tech. told me the sock is for very heavy sand/dust exposure.

Be sure you oil the 25-0880, but don't overdue it or you could have excess oil run onto the RE, and might suck it through to your turbo.

I have a very bombed 97 Dakota gasser that has an air-intake system with a cone K&N at the end of a stainless steel intake tube, with the cone pointed at the front of the engine for coolest air source. In 15K miles of street driving only, the K&N looks like the day I installed it. For my use, I think the 25-0880 is overkill, but because of all the TDR warnings I'll stick with it.

hope this helps.

thanks 24V-DSL--I did oil-spray on inside & out & then tried to squeeze the excess out--not sure if I've got too much or not--I was a little oily after I put it on--would that be a sign as too much--it wasn't dripping---I'm not sure I'd use the sock-do you have to oil that thing--little cleaner if you don't----thanks again--chris

I'm not sure about the sock...

With my 25'r I oiled inside and out... . lightly, and let it sit for a few days to see if it would pool. It didn't, so, since it was oily on my hands to handle, I wiped it down again with a couple of towels, inside and out before install. I used to over-oil my K&N's on my gassers and ended up with a mess. Finally got the picture by looking more carefully at the pleats of the new filters..... they look like they're not oiled at all.

If you weren't drippy I think you're fine.

I removed the Pyschotty and went with the foam pre-filter. Oil analysis results indicate I have significantly less silicon now; got about 9 in 5,000 miles before the pre-filter, down to less than 5 in 5,000 miles after the pre-filter was added. I like my present set-up, but I'm a little concerned that when summer gets here I may be sucking hot air from under the hood and have trouble cooling off the turbo. "Testing" will continue... #ad


P. S. - The impression I got from K&N was that the sock was good for "big stuff" and because it was the easiest to remove for more frequent cleaning in a high dust environment, but that the oiled foam did give better total protection. What have others heard?

Our new home constuction company recently hired a diesel mechanic since we have over 40 gasser 6KW generators, and 3-25KW diesel generators to maintain. This is in addition to two big Volvo's with 8. 3ci Cummins and a 1 ton International dumptruck.
The Volvo mechanic has let me read a "College" diesel repair manual, and I've read several things that the TDR might enjoy learning about diesels. I'll post a blurb @ K & N filters for a start as I have a 'K&N' filter-charger installed in my 3500.
>The text book states the following:
"The oiled air cleaner is seldom used now because it is less efficient at lower engine speeds when the airflow entering the engine is lower. This lower air-flow reduces the agitation of the oil within the air cleaner and , therefore does not trap airborne dust... . In addition, over oiling can cause engine overspeed. In cold weather, the oil can freeze; the result is high air inlet restriction and/or poor dust/dirt trapping ability. There's more but I'll wait for questions or comments.

very interesting-what year is the book and what do they suggest? & give us more!! chris

 

[Brandon]

are we sure "The book" isnt referring to an oil bath type filter old school style

Ordered a K&N cone type filter today. Been reading all the pros and cons on here for months and decided in favor of it. I had one on my 93 for 120K+ with good results even though I spend significant time on dirt roads-------never saw any dirt on turbo bades. I went with the RX 4070. Its the RE 0880 but with the end made of filter material as well.

Best part was the PRICE; way under any I had seen here or elsewhere

Check out Performance international 1-800-522 1672. Filters appear to be their primary business.

Brandon, You are right, it's referring to an 'oil bath' type air filter, not a K & N type.
This diesel school book is making me want to take a college/tech class on diesel engine repair just for kicks. #ad

 

[Jonz]

Just curious...

Has it been tested to show that these cone style filters make a differance? What would that be. Also, the K&N is designed to allow dirt to pass so as to never clog. They were designed for off-road use and to keep the vehicles running. With this in mind I think the sock or filter skin would be very well worth it.

Just a thought.....
