Hi can anyone tel me if K&N 57i cone filters are any good, thanks

 

I've been hunting for reviews on the K&N (57i-4000) Generation II Induction Kits myself and have only come across good reviews.

So I'm thinking of taking the plunge and getting the kit, with the K&N Induction Kit and the Afterburner Vortex added to my car it should sound and feel good.
