I just recieved an E-mail that I sent out (3 weeks ago) to k and n about when a air filter will be avaiable for the cannondale. they said that they WILL be working on it soon and check back in a couple of months. so that tells me, not going to be this year../

 

i would have though they would have one out by now for sure .

 

I like the foam filters much more. I don't know about the filters for quads but, the K&N's for cars seems to let dirt pass through. I posted a topic about what Amsoil said on their website, and quite a few people replied back talking about how they had problems with dirt getting past their K&N filters in their cars, and a few had problems with their quads.
