hi guys i really want to change my air filter but i am not sure what to do about the sensors which plug into the standard air box.
i am looking at BMC CDA filters because i know that cold air induction kits are better, but looking at the ones which are apparently for my car online (318iS) they have nothing about the sensors. im pretty sure its an air flow sensor so i want to make sure its working properly in a new filter.
also can i not have any suggestions from people about open filters because i know they are a waste of money and i wont even consider them :P
if anyone can help it would be greatly appreciated.
