I have a 2011 Ford Fiesta SE which is due for a new Air Cleaner. Could someone tell me how to install it? Also, the Air Cleaner cover is held in place by 4 bolts which must be removed by an Allen wrench. I have never seen anything like that before. All my Allen wrenches are about 4-inches in length and in order to remove the 2 bolts on back of cover I need Allen wrench at least 6-8 inches long. Any Suggestions?
