So I finally decided to put an S & B cold air intake into my 2009 F 250 and one day after the install my check engine light comes on. I decide to take it to Auto Zone and get the code read and basically the DPF filter is causing the code. Needless to say I keep driving the rest of the day and take it to my dealer the next day. After talking with the mechanic he tells me the truck is putting out several codes, mainly the DPF, but he believes this all has to do with the new intake........now I'm no mechanic but I'm unsure how they can try and pin and cold air intake on an exhaust issue.....Now he's telling me that I will be lucky to get my truck back by Monday!!!!! Guess I just need some input on how to deal with this issue...
