I pulled my silencer off my SE and put a K&N in the stock airbox. After the ShoShop Y-pipe install, I am going to take off the stock airbox, cut a large hole in this and the inner fenderwell, install some aluminum ducting and route it down to the airdam area.
I am not one of the "KKM" supporters due to heatsoak issues. Total cost:
$6 home depot aluminum ducting
$1 jigsaw blade
$35 K&N panel filter
no heatsoak is good, esp this summer!
