The purchase of a Lincoln car is an investment in a powerful automobile that is roomy and luxurious to drive -- so maintain that investment with the simple and easy act of replacing the Lincoln air filter. Normally, the general rule of thumb is to replace your Lincoln air filter every 10,000 miles or so. However, make it a habit to check your air filter every month or so for clogs. Sometimes, very windy or wet conditions can age an air filter faster than the norm. Moisture will make a filter lose its shape and hinder its ability to screen out dangerous matters. Dirt (brought in from the wind) will clog up the filter. So, if you see a buildup of dirt and oil on one side of the Lincoln air filter, then order a new filter here and replace it yourself. Why pay a dealership top dollar for parts and labor, when it only takes a few minutes to do it yourself? The duty is very simple: In a vehicle with a fuel-injection system, the Lincoln air filter is located in an air-cleaner housing. That can be removed by removing a screw or releasing the clamps. Then, pop the old filter out and pop the new filter in! It's easy and economical.
