If you are experiencing engine problems like sluggish performance, stalling, a drop in gas mileage, or hot running, have you checked your GMC C3500 air filter recently? The air filter is an essential part of your engine that needs to be replaced regularly. You will find your C3500 air filter located near the top of your engine, making it much easier to access than the other filters on your vehicle, such as your oil filter or fuel filter. This means you should have no excuse for not regularly checking your air filter.

The job of your GMC C3500 air filter is to remove dust and contaminants from the air that is entering your combustion cylinders, where it mixes with your fuel to burn and generate power. Your engine needs clean air, and plenty of it, in order to be able to run well.

Unfortunately, the appearance of your C3500 air filter can often be deceiving. Your air filter may look clean, but still be too full of dust and grime to be effective. The best way to test your GMC C3500 air filter is to remove it from the plastic housing and blow through it. If there is air passing through the filter easily or with little resistance, then it should be all right for a while. However, if no air is getting through the filter, then your engine is not getting any air either. You should replace your C3500 air filter at least once a year, and it is a better practice to install a new air filter with every other oil change. You may even want to invest in a high-flow performance air filter, which is washable and reusable so that you don’t have to keep buying new filters.Find the air filter you need in our extensive online catalogue.
