This baffle has a larger opening than my stock '03 and it also has a deflector at the bumper level which allows ram air to enter the opening. The stock '03 only draws air thru the gap between the headlight and the bumper. Adding this baffle also allowed me to get the '04.5 & up PSM cool air kit which is $40 less than the '03 and requires no drilling into the bumper or fender. Baffle was $9.60 at the local Dodge dealer.
