I installed my K&N Typhoon today in about 30 minutes. No issues, no problems, extremely easy installation. There is no noticable sound difference untill about 2200 rpms, then WOOOTTTTT. I don't know about 16hp but you deffinitly feel some gain form the intake. The strut bar was a 1,2,3 installation as well. Torqued down to 16 psi and at speeds of 40+ there is a noticable difference handling. So far these 2 products are must haves for the SS.
