Anyone used one of these before? The HE or the R version? Or am I better off just using standard filter?
Good filters but not on the Blade, cause the shape isn't good for our airbox .... ( i can talk about cause i owned on before ) if you want gains go with Pipercross race or best to my eyes : sprint filter .
Would you get any gains at all from an air filter? At least any gains that that the rider could notice?
You could get gains only with a good remap of your pc5. Yes with the Sprintfilter, good midrange gains of torque.
issue is the material, coton are great but after few cleans service, it goes bad. Seriously, try sprint filter, it's a unique lifetime air filter, i wash t with compressed air and still new !
There is nothing wrong with k&n as far as im aware but I've been told you don't get any extra bhp though by using one
