Umm...I'm not following you Nuru...are you For or against K&N's?
What I'd WANT to do is use a K&N on the Cab...not the engine. I have no intentions of using a K&N on my tractor engine...
My experience with K&N's is a great one..got one on all the street vehicles we own. BUT...in dirt applications, I think we're best off with a quality replaceable paper element...
As for cost...most K&N's are in the $30-$35 range, sometimes more... Deere wants $25 for their cab filter...K&N's are good for 10+ Years...
As a side note....my Cab air filter was 5x more dirty then my engine air filter...which I thought was interesting...
Spudland_Dave; Nope i am not recommending using K&N for our applications, but I would like to know if anyone has used them. On another thread, somebody indicated that the diesel pickup truck forums did not like them for filtration. So that makes me even more wary.
