The engine air filter plays a vital role in protecting your engine as it stops various debris particles from entering and causing damage. As debris adds up with every mile traveled, the air filter will reach its maximum dirt absorption capacity at some point. When this happens, the air flow resistance rises and affects the engine’s performance. So, it is important to replace the air filter at your vehicle’s specified maintenance interval. However, you may need to change your air filter sooner depending on your driving conditions.

This is a very easy DIY that even a beginner can do. It will also save you a lot of money versus going to a dealership. For an overview of how to perform this DIY procedure, check out the tutorial above from the YouTube channel, Cars+Raf. More detailed instructions can be found below.
