thanks!!! so how will i really change it? i'm about to purchase the k&n drop in panel filtr on my diesel...

another question, i'm about to change my battery on my diesel... the dealer said that i should be getting the oem battery because it is different from other brands... is it true? i found different brands with the same specs (size, rating, etc) as the oem batt... but bmw still told me that thier oem batt is different...

thanks thanks!!!
