Whose yer DADDY!??!?!?!?!
Anyone have one of these? You know the aftermarket intake system that K&N manufactures? How often do you clean the filter? According to the manual they say that you should not need to clean it more than once every 40,000 miles. I dunno if I agree with this, as mine is extremely dusty and kind of horrible to look at.
What are your thoughts?

K&N have their own filter cleaning fluid and filter oil. You'll need to get both of these.
Just read the instructions, it's easy to do.
 
No I have the "re-charge" kit that comes with the filter and pipe, but it says to use it every 40,000 miles or so, and that as dust and other crap accumulates in the pleats it actually helps it filter the air.
This just sounds like bad advice, but I mean, they are the manufacturer so who would know better right? Someone told me that if you oil it to often you run the risk of screwing up your MAF. So yea, I was wondering if anyone else has one and cleans it regularly and whether or not it has messed with the MAF in their car.
 
I have one and i just clean it when it looks dirty and try not to over oil it.. Normally i'll just give it a light oiling and let it sit for over night I put paper bags uner it if you get oil on that you'll get oil on the MAF so strive to keep it oiled lightly this is a time where more is not better..
 
I typically do mine once per year, in the spring. They do raise the silicon levels in my oil, so filtration isn't their strong suit. I figure by keeping it clean and oiled (without over doing it and causing damage) helps minimize that.
 
If I can make a suggestion....sell your K&N for an Apexi oilless cone filter. They have been proven to flow better and filter better without the oil junk. I bought one a couple years ago and love it.
 
When I used them on a couple of turbo Talons I had, I cleaned them annually.
On the GTP, I just used the K&N with a modified, (gutted), airbox and still did the annual cleaning thing.
Then I read quite an in-depth article regarding their filtering efficiency and I now use a stock paper filter.
As noted in a couple of previous posts, the K&N didn't fare too well in the filtering category. If I were racing and the engine was torn down and rebuilt regularly, I might use one but when I run my vehicles in excess of 150,000 miles before I replace them, I don't think they are for me.

What are the ill effects of having an aftermarket air-filter? Did a bunch of gunk get in the heads or the intake manifold or something?

And Bob, how do you clean the oil-less version from Apexi? With a vacuum? I am actually interested in this and have never heard of it? What do they run dollars wise?
 
The article I read mentioned abrasive particles in the oil that the testers felt were getting through the K&N filter.
Scott P's "raised silicon level in his oil" is likely due to dirt/dust getting through the filter.
The effect would be more wear on your engine due to those contaminants.
How much more wear, I have no idea. I just felt that any more was too much.

It's very possible that the wear would never be a factor in the time you own the vehicle.

You just shake them out or vacuum them. They are a little more pricey than the K&N's but you never have to buy a recharge kit and they filter better so it is worth it in my opinion. Here is a link to some filter testing i found helpful.

Some have said to avoid reoiling a K&N as much as possible, and just to take it out every couple thousand miles and knock it against a wall or something to get the big particles out.

Yeah, this makes sense. I had a K&N on my GMC Sonoma and hated it. No matter how little of oil I used it always gummed up my throttle body.
 
I have been running K&N FIPKs in all my Jeeps since 1999 with no problems. I will clean mine when they look dirty. This may be twice or more per year. One of my Grand Cherokees has 174K miles.
 
K&Ns let a lot of dirt in to you engine I have one, but won't get another. Most don't give you much of a benefit. A lot of air box kits like FIPK change the way air moves through intake fooling you ECM into thinking there is more air and the ECM dumps more fuel in to make up for it. Reoiling has never been a problem for me.
 
I have a drop in K&N and have never oiled it. I've had it for maybe 4000 miles, i doubt they really give you any HP, but dont oil it too much, cause it could clog the MAF.
 
I had a k&n on my old Chevy truck for 165,000 miles before I sold it. I have one now on my new grand prix. My old truck blew better on the sniffer test than my mom's newer grand marquis. It's all in proper care and maintenance as far as how they do with regards to the oiling. It's just like any other part of the car...neglect it too long and you'll have problems.
