Default Thrasher, Fenderwell or Gutted???

OK, Which is the best way to go? I want to Maximize Airflow and HP as well as hear the Supercharger....

1) "Thrasher Engineered Performance Cold Air Induction Kit" $214.99

2) INTENSE™ Fenderwell Intake Kit $179.00

3) Gut my existing Air box and us a K&N filter $45.00

#1 claims 10 - 15 HP gain conservatively

I also plan on changing the pulley to a 3.40 as well as adding an INTENSE™ Reprogrammed PCM

Any help would be appreciated.

SLE, on the Intense FWI, is there anything that secures the filter in place? Or is the fit through the hole in the firewall tight enough to keep it secure?
