I'm thinking about going with a K&N filter. I do all my riding in the sand. do you guys think it will be alright to run a K&N filter in the sand. Or Should I go with a foam filter instead. I prefer K&N filters but I'm also concerned about reliability. thanks for any responses.

 

I dont know if there is a better of the two for sand, but I run only K&N in all my bikes and we run sand only. Havent had any problems.

 

You may be right, however, I work for Cummins and we have tested the K&N filter vs. the (OEM) paper filter and the paper filter did a much better job. So much so that you will void the warranty on your Cummins engine if you use the K&N. There are really no tricks to airflow, its like fuel economy vs power. You increase one and the other suffers. You increase air flow for more power and you will lose filtering capability.

 

Foam elements for maximum protection
Paper or gauze style(K&N) for best air flow

 

All my friends have run K&N filters in their banshees with no airbox at all for years and none of them have ever had any problems associated with it...I've run it for a little over a year now and all i ride is sand and have never had a problem either...

 

Id go with the K&N. They put out more power and they are easier to clean and maintain(my personal opinion). Ive run a k&n since the day I got my rappy and never had any problems and I run only sand.

 

always ran k&N's and they are easy to maintain

 

Everybody always asks about sand. Sand grains are pretty large and easy to filter compared to that fine dust that is like talcum powder. In the stuff I ride, sand is the least of my worries. On the other hand, sand is very abrasive and would ruin an engine real fast.

Anyway, I have run K&N's w/ outerwears on everything for many years with no problems. I do change the filters very often though!!

 

K& N "with" an outerwear works fine in the sand. As Reconranger noted, due to grains of sand being so much larger than dirt particles a
K & N filter will do the job for sand. Now if you were going off on a weekend dirt excursion, I'd bolt on a 2-stage foam filter.

The outerwear is mandatory. It keeps most of the sand from sticking. Without it the gauze will pack up and sand will get in.

Foam filters pack up quickly with sand. You'll want an outerwear over a foam filter as well. Problem is, the oil on the foam gets on the outerwear and it plugs.
