I ran a K&N on my Duramax until I had an oil analysis done. It showed everything normal except an elevated silicone reading. May need to find some type of foam filter that breathes more than the stock one.

Yes, Im going to switch to the Uni-Filter myself. Its easier to clean and more suited for off-raod conditions IMO....

...I just always refer to the K&N because its what most people know.

Uni-filter is the way to go off-road.

I have the Uni-flow and it is a very nice filter.

K&N filter's aren't what they are talked up to be in my opinion.They dont restrict enough.They allow alot of dirt and particals to pass into the engine.If you do run a K&N you need to run a Outerwear,but why pay $50-$70 for that when you can get a UNI for $25 and have just as good of a filter that protects better and flows just as good?

 

[dickmadison]

Any suggestios on where to get a Uni-filter? Does the DJ jet kit address using this filter or just the K&N?

The Dyno kit only specifies a difference in "exhaust" for jetting, and not filters if I remember correctly...the Uni-flow will do fine.

Duramax,How does a K&N add Silicone to the engine? Do you mean Silica??

As far as filters go..If have to decide if you want more flow or better filtration..
Nothing flows better than the K&N, And it can filter well, it depends on how much oil you put in it and how much dirt collects on it, the dirt actually increases filtration..

The Uni-filter does filter better, but the cost is flow, it does not flow as well, it is a compromise.. not a bad choice, and certainly a bargain..but you can't have the highest flow AND the best filtration!!

Duramax,you can get a UNI from Rocky Mountain ATV..

Duramax, I will agree with your observation. I had a K&N on my 400ex when I raced and in dusty mx conditions it left a sandy residue in the intake tube. I switch to a uni and the residue went away. I have decided to stick with foam on the dirt.

I bought a Uni-flow today...I just got the Rinny back from the shop. It just wouldnt move and I didnt have time to look at it much.

Turns out carb was dirty. A good carb cleaning and she's as good as new. Ill stay with the Uni-Flow...

...I know it wont flow qiute as much as the K&N, but when riding off road in dirt/dust it will keep more trash out.
