OK, I have heard a bunch lately with K/N and over oilings happening. Some are "factory" from K/N.

Question: How can we prevent this from happening short of not using a K/N in the first place? If it comes over-oiled from the factory, how can I tell?

Right now I am paranoid putting mine on for fear of damage to sensors. Since I have not put K/N in many of my cars, I cannot tell on sight if its over oiled.

I am not willing to mess with expensive sensors over a 1-x HP gain. But eventually when other mods come along I will need to get an easier breathing air-intake so.....? What to do?

 

I've been about as parnoid about adding stuff to my max as you are. I'd just put it on.

 

When mine was over oiled (from the factory), the bag that it was wrapped in had oil all over it, the chrome fitting on the end had oil all over it, and there was some oil inside the cone. Since this was my first K&N I assumed this was ok (it was from the factory for Pete's sake!!)...I was wrong. However, the guy at K&N said he has heard of this happening before, but on very rare occasions. K&N was very professional on how they handled me…I would still buy their products.

K&N has since sent me a new air filter and the new one is totally different. There was no oil on the bag, chrome cap, or on the inside of the cone. The filter should be red, but it should not feel wet. I think I am going to hook up the shop-vac to it as well to make sure to suck out any excess.

Good Luck!!

I got a little paranoid,too, after seeing a few threads here. So I took off my MAF from my CAI and checked it. It was a bit dirty, only due to black carbon on the mesh screen, no oil at all. It was fine. I wiped it off with a cloth and blasted the whole MAF with electronic parts cleaner. The difference between clean and dirty was not that much at all. Now the mesh screen is shiny gold. My K&N is A-OK.

hey, I recently post a thread about this and I have found some black particle on the clean side the the air box as well. The factory oiled filter did not overflow to the clean side. However, when the time I cleaned it myself, I overfilled it b/c I was affraid that not enough filter oil will reduce the quality of clean clean being produced by the K&N. But a lot of oil when thru to the clean side. I asked a friend of mine who use K&N for 10 years and he suggested that after you cleaned it, dried it (whick takes a day or so for it to dry completely) and then soaked it with oil. Do not use it right the way, let the thing soak for a day.

One thing good about maxima is that the opening is on the top of the box, where overfilled oil will most likely trapped on the bottom.

 

After having to replace my computer.....(insert long streams of cussing).. I do not have the cabbage to replace MAF or anything else....So thanks for putting my mind at ease...

And if it does give me problems....I blame ALL OF YOU! LOL

J/K of course for those that don't get my humor.

 

dwapenyi:
do u know why do "we" get those black carbon particles on the mesh screen? I get those too....and I dun have CAI, but OSCAI. I just get an update from Adboy and he doesnt have anything on the screen at all....

so....is it bad? are we doomed?

 

I don't think we're doomed at all. The dirt that was on the screen accumulated after 80,000 miles of driving. I wnder how long Adboy's interval was. The last time I cleaned my MAF was when I installed my CAI. UN-like the POP filter, when you clean the CAI filter, it's way below the MAF. For the little dirt that was there, after 80K miles, I have no worries.

I don't know where they come from either

Adboy and I have about the same interval....where our K&N and OSCAI aged at 20,000.....he didnt have anything on it, but I do and only for a car aged 20,000 of use of K&N and OSCAI. A friend of mine suggested of engine backfire.....

I dunno, going to double check again, thx for the advice

 

Maybe you drive more highway miles than he does, oil change is less frequent than him

Just clened my K&N last weekend. I'm sure the first time we all clean the filter, we will over-oil it. What I did to compensate for over-oiling, I placed the filter on top of a stack of newspapers, and let it drip. It even dripped into the inside, so I took a paper towel and wiped off the excess. Do that severl times and if you let it rest long enough, all excess oil should come out. This I did from reading all you guys posts.

 

You're probably right. Alot of us may also get too impatient with the cleaning process. When I cleaned mine last time, something came up and I couldn't wait for it to dry, so I took a blow dryer to it. I know, I know, that could shrink the cotton fibers of the filter by drying too fast. I kept the dryer at least 3 feet away from the filter but pointed directly at it. Kept the heat at the lowest setting. Took about an hour to dry.

From now on, I'm just getting another filter to use temporarily while I let the K&N take it's time cleaning and drying naturally.

agreed...cleaning filter is not going to be a one day event...I would give it at least 2 - 3 days. it takes at least 1 day to dry the filter and 1 day to soak it with filter oil. Never dry it with other methods but air dry....other methods might ruin the pores of filter and reduce its filtering abilities. I always keep my stock filter and use it as buck up.

 

This is not brain surgery folks. The instructions are very clear on the cleaning solution and re-oiling spray can.

I clean the filter at night and leave overnight. Then spray the filter the next day(ONE PASS ONLY W/ THE CAN!!!!!!!!!) Let it wick for 10 min or so and spritz the spray on any parts of the filter that's still white(ish).

Very simple, very easy. I've done the countless times before. For the love of everything holy, don't drown the filter in oil.

 

I overoiled my cone K&N on my other car real bad with no adverse effects.

It was so bad, I thought I had a tranny leak under the car, until I found the filter was dripping that red oil.

I oiled the filter and then reoiled the white spots. Problem was I did not wait long enough for the oil to wick through the filter.

The car is fine, and I know for my Max.
