Take a look at this page of K&N filters.

Go down to the 2005's and look at the Turbo filters. One choice is the Typhoon the other is the FIPK/Aircharger. Notice the FIPK/Aircharger has surrounding baffels to stop hot air from being sucked in, whereas your Typhoon is just a tube with filter. If your trying for every bit of HP, even though the FIPK/Aircharger will cost more, that's the way to go.
