Ques. about dinan website?
 

I was on there looking at there parts list and it states that the cold air intake is for 2003 to 2006 models. But the valvetronic engine started in 2004. Is this a typographical error. Or is there something i dont know about the 03 4.4 that makes it use the same air intake as the 04thru06s

The Dinan PDF catalog shows the same thing. Throttle bodies and exhaust show different part numbers for '00-'03 and '04-'06 models, but CAI shows '00-'03 and '03-'06. It must be a typo.
