Ehh hard to say
,the 04-05 can be strange beasts when it comes to messing with the air intake.The gotts mod also increases air flow but im sure not as much as the K&N will. The K&N to me will add much more air flow than stock and the Gotts mod. With more air flow than the Gotts i wonder if a custom tune will need to be built. This will be best answered by bill. Very unique question!
