Go with the sho-shop "cold air intake", it runs around $140 I think and it basically is the KKM with a heat shield. Any open air element filter is going to get that sound, if you cut your stock airbox you get the same effect. You're not really going to notice any difference really in hp or how fast the car is. I have a KKM and now I wish I got either the Sho-shop cold air or pieced together my own custom intake. Jus my $0.02.
