Stock replacement K&N Air Filter?

[99xcsp]

Hi, Newbee Here!. Great Forum.

I recently bought a New 2013 Kawi Voyager. (Love the Bike) Put the Cobra Slip On's on along with the Cobra FI2000R tuner, bike run's good, has some little decel pop like everyone talks about, no big deal I'm used to it, rode Harley's for many years, they all had it, even with some great Dyno tunning.

My question is about a K&N stock replacement Air Filter, Is it worth the money?..Any kind of performance Benefit? they always seemed to work well with the Harley's, just not sure about this bike.

Thanx!
