New air filter time
 

Im simply looking to replace my standard yamaha air filter on my xt660R.
K&N obviously have a brilliant reputation but should i look at anything else? I have beowulf cans fitted so thought i should sort the filter out too. Will replacing just the filter give me much more performance results? I have read alot on here about various "stage" filters but i just get confused by it all as i'm not the most engine orientated man in the world!

Cheers!

think ihave a k&n filter off my r still in the shed and still for sale.
made a difference to my r running with metel mule 2 into 1.

DNA are Dyno proven to flow more air & produce more HP than the K&N filters, the + side of the K&N filters they are cheaper.
