If your engine is running rough, getting fewer miles to the gallon, or putting out excessive heat, you may have tried everything from an oil change to a full tune-up with no results. Have you considered that the cause of these problems may simply be a dirty air filter? The Cadillac XLR air filter is a simple part with a simple job: it keeps dirt, dust, and contaminants out of your engine’s oxygen supply and lets your vehicle “breathe.” However, it is just a filter, and that means it’s going to get dirty over time. Unlike your oil filter located in a hard-to-reach area under your engine, or your fuel filter nestled inside your gas tank, your XLR air filter is fairly easy to get to.

You will find it near the top of your engine, just sitting inside plastic housing. Since it is so simple to get to, check, and replace your Cadillac XLR air filter, you should have no excuse to run your engine with dirty air.

Keep in mind, however, that you can’t always tell whether you need a new air filter simply by looking at yours. The best way to test your air filter is to remove it and blow through it. If air is getting through the filter, then air can still get to your engine. However, if nothing is penetrating the paper fibers, it is time to replace your XLR air filter. You should install a fresh air filter at least once per year, or more often if it becomes clogged faster.In our extensive online catalogue you will find a full line of XLR air filters as well as high-flow performance air filters that are washable and reusable, and provide your cylinders with more oxygen for smoother running.
