what aftermarket air filter do you recommend? i`m jetted and snorkeled



damn, it sounds mature in here! back to normal. i like it.

 

I have the K&N and like the way it is working for me. Pretty good design for the Kaw air filter.... Good power upgrade

 

TwinAir dual stage foam filter. Dennis Kirk $23.

Great air flow (identical to K&N) but with much better protection. Its always very dusty on the trails here. I want to make sure I can do what I can to maintain the 650. I feel better with the additional protection compared to K&N. Not to knock K&N, but it's just a personal choice. I use K&N in my truck and had one in my Honda CBR F3, both worked well.

 

Is there a test somewhere that shows the twin air flows as well as the K&N? I have read the comments on K&N not filtering as well, but flowed better.
