Your BMW 528 Series air filter may not look like much, but it is an important part of your engine that should be regularly maintained. The 528 Series air filter is responsible for removing contaminants, dust and grime from the air supply that is entering your combustion chambers, in order to ensure your engine burns clean. Of course, over time the dust and contaminants will build up in your BMW 528 Series air filter.

Once you have a clogged 528 Series air filter, the consequences are greater than a little dust in your engine. A dirty BMW 528 Series air filter can lower your fuel economy, reduce your car's performance, and cause your engine to run hot.

Excess heat is damaging to your engine, and so a clogged 528 Series air filter can lead to more expensive repairs if it is not replaced. You should replace your BMW 528 Series air filter at least once per year, even if it does not appear dirty. This is because your 528 Series air filter may look clean, but still be blocked with nearly invisible contaminants that keep it from doing its job. The most effective way to check your BMW 528 Series air filter is to remove it and blow through it. If the air passes through your 528 Series air filter with minimal resistance, it is still working to block dust and grime from your combustion chambers. However, if little or no air passes through the filter, it is time to replace your BMW 528 Series air filter. You may also want to consider investing in a high-performance 528 Series air filter that is washable and reusable, so you don't have to keep buying more filters.Browse our online catalogue for a wide selection of BMW 528 Series air filters and performance 528 Series air filters.
