What are those?

 

I agree with Cebby. I have used K&N products for over 15 years and have had no problems. My 86' had over 400k with a K&N. The key to the filters is not to over or under oil it.

 

How often to those who use K&N do you guys clean and oil?

 

Every three months usually just an oiling. 6 months for a full cleaning. If I was out in some really dusty conditions, then more frequently - and it would be a full cleaning not just an oiling.

I've been at it so long that I can be done - start to finish - in about 10 minutes.

 

Hey Cebby..what do you have to do to clean it? just just the cleaner...wash it off with water..let it dry..then oil it?

 

Pretty much. The cleaning process takes the longest since I like to get it really clean. To get the excess water out of it, I shake the water off, them let it sit in the sun (I do this on sunny days usually). Then oil it. I use the spray oil. THey used to have oil in squirt bottles that I found wasted too much oil (and made a mess)

 

Yup, pretty straight forward. I do it at night to give the filter longer to sit out on paper towels to help leach any excess oil.

 

I started with K&N's on my street cars. They do offer quite a gain for just an air filter, but they do not filter enough for off road use, plain and simple. I can't tell you how many times I see an open element air cleaner with a K&N in it, with an Outerwear wrap on it. The smart guys do it, because you will have alot of sand sitting on the base of your air cleaner.

If you know how an old style V8 air cleaner is shaped, it's like to plates with the filter sandwiched between. After a trip to Silver Lake Sand dunes www.silverlakesanddunes.com I went to clean my K&N. I found quite a bit of sand laying on the inside of the filter, and it did seal up perfectly.

K&N's provide a great boost for the money, but don't filter as well as an Amsoil, or even a paper element. If you're a street only kind of person, go for it. If not, and you still want to run a K&N, I highly recommend the outerwear wrap for it. Why else would K&N market a product for dusty conditions that goes on the outside of the filter?

 

Vmax-

Just curious about your user name- any biochemical reference there?

 

question to those with '03s...when i first put my k&n filter in i was lookin at the cover to the airbox and inside it there is a white filter looking thing. Is this like a second filter? Because you take out the air filter then there is this directly underneath the cover...i was just curious about what it is

 

I have the TRD one. I can clean it every 3-4 months, I pulled the MAF and it was spot less.

I could care less about the HP gain, blah, blah, blah. I bought it so I could wash it. Arizona is really dusty.

Of course with all of these filters if your not smart enough to oil it correctly stick with disposables.

Don't be the lady that sued McD's because the coffee was hot.

 

Well said.

Nope! Think snowmobiles, as in Yamahas. I've got 2 '00 Vmax 500's, tons of fun!

 

Ahhh. Never mind then- just being a nerd for a second, Vmax describes the maximum rate at which an enzyme can catalyze a chemical reaction.

 

So what's ZMAX mean then Goodspeed?

 

Vmax: I agree. I have run a K&N in my Runner for the last 9-10 years.....and mostly this has been on the streets..... and I still need the outer wrap!!!! I clean AND maintain that filter but when I did the ISR mod, I found all sorts of crap in the intake and throttle body......I found dust, grime........I thought I was going to find Jimmy Hoffa in there! When I get a new Tundra 4x4, I'll get a TRD or a Amsoil for it.
