Has anyone fitted the K&N filter, has it improved performance. ?

is it worth it.!!!!

Just change the paper filter every 10k rather than 40k miles, you don't have to tell the insurance about that like you do a K&N and it will make about as much difference as the K&N.

I run a K&N and claimed improvement is up to 5bhp, but I'm not convinced. Does make the car sound better though, and lasts 10k between cleans so cheaper if you're a high mileage driver

My insurance charged me no extra for it
