I finally got my dealer to admit that a TSB for the "tick" was not a hoax. I have an appointment next Tuesday. One question....I have a CAI installed. Will they try to tell me that the warranty is voided? I can't put the stock air box back on because I cut it to shreads trying to get more airflow with the stock filter. I would reather buy a new stock air box from Ford that a new head from Ford. Any suggestions would be greatly appreciated. thanks.
