I bought the K&N typhoon intake and ran it for about two weeks. I then bought the Accesport and didnt want to pay for a custom map so I replaced this intake with a Perrin intake. I would now like to sell this K&N. The car and driver article dynoed the intake at 17hp and 21 pd/ft at the wheels gained. K&N claims a 14hp gain for the 08. If anyone is interested in it PM me, I paid 350$ when new.
