So, your engine is sluggish and running hot. Your gas mileage is suffering. Maybe your engine is stalling out, or you’re having difficulty getting it started.

You may have tried cleaning your fuel injectors, changing your spark plugs, or even switching to a higher grade of gasoline, but have you checked on your Ford Thunderbird air filter? If you haven’t changed your air filter in a while, chances are that is what’s causing the problem, or at least contributing to it. Your Thunderbird air filter rests near the top of your engine, where it is responsible for removing dust and contaminants from the air that mixes with your fuel in your cylinders.

Of course, since it works to remove contaminant, over time your air filter is going to get clogged and dirty. You might have looked at your Ford Thunderbird air filter recently and thought it was fine, but a glance at an air filter isn’t always enough to tell whether you need to replace it. Even if your Thunderbird air filter appears clean, it still might be too clogged to work properly. The best way to check your air filter is to remove it from the housing and blow through it. If air passes through the filter with little resistance, it should be all right, but it no air is getting through, then no air is getting to your engine. At the least, you should change your Ford Thunderbird air filter once per year, and it is even better to put in a clean air filter with every other oil change.
