Your engine is a marvelous machine, taking in fuel and exploding it in order to harness chemical energy as mechanical energy. However, for this to work, you need oxygen, and your car gets that from the outside air. As we all know, the air outside can have everything from smoke to pollen to even an errant bug in it, and combustion does not handle contaminants well. That’s why you have an engine air filter, and when that air filter gets clogged, we’re here at our service center to help you replace it.
Your engine air filter is full of tiny holes that are big enough to let air through but small enough to keep most other things out. It’s much like an orange juicer that lets juice through the holes but keeps seeds and pulp above the cup. Much like an orange juicer, your engine air filter can filter so many things out that they end up blocking the majority of the holes, decreasing the amount of air that comes through. When this happens, the ratio of oxygen to fuel is disrupted, causing decreased efficiency and even misfires.
Aside from misfires and decreased fuel efficiency, you might also notice some other signs of poor combustion in your car. If it’s quite bad, the check engine light can come on, alerting you to the need. You might also notice thick black smoke coming from the tailpipe, or strange sounds or fuel smells coming from the engine, especially on startup. All of these can heighten your suspicion that you need an engine air filter check, and our certified technicians are happy to check it for you to confirm.
It means a lot to us that our technicians are certified. It means we can trust their level of care in your BMW, it means we know that they know their car repair and maintenance, and it means we can trust their service to last. The best part is, you can trust them too. It’s not easy to give your car to a stranger to fix, but you can treat our technicians’ certifications like a stamp of approval, easing your fears and reassuring you your car is in the right hands.

Your engine air filter is an important component that keeps your engine functioning at its best for you. We’re ready and waiting to help you replace yours if it’s gotten clogged or saturated with foreign substances, and we’ll make sure it’s replaced with the highest attention to detail possible.
