An air filter for a 1999 to 2003 Ford 7.3L Powerstroke is an inexpensive part, so you may not be giving it much thought. However, there are several reasons to pay close attention to this seemingly minor component. The air filter is one of your engine’s first and seemingly most important lines of defense. It stops small, potentially damaging particles from making their way into the cylinders. These particles would, at best, pollute your engine oil and reduce its effectiveness. At worst, they could damage the engine’s seals, pistons, cylinders, and other internals.
Therefore, selecting a good quality filter from a brand like Banks Power, Mishimoto, or S&B Filters is vital. Norcal Diesel Performance stocks filters from all of those brands. The filter is also a part with a limited service life and should be replaced every 15,000 to 30,000 miles with standard use. However, if your truck is often in dusty or polluted environments, you may have to replace the filter more often. If a filter is clogged, you will start to see your truck’s performance degrade as it struggles to pull in enough air.
