I hope this is the right place to post this, i dont get on forums alot.. I have a 2013 Focus ST2, i daily it and its my child. The past 2 days in the morning for work my car has been dead as a door knob. I was told my battery could have a bad cell. Well i brought up that my fuze box ticks...

I have K&N Cold Air on now and would like to get a factory Air box for the 2003 SVT Focus
