O2 Sensor Replacement

Ask any of our auto parts specialists at Morningstar Auto Parts and they will tell you to have your O2 sensor inspected regularly. Oxygen sensors work in conjunction with your catalytic converter to monitor the amount of oxygen in your car's exhaust system. Your O2 sensor determines if your air to fuel ratio is balanced in real-time as you accelerate or idle. It helps your engine controller adjust the flow of fuel to maintain optimum oxygen to fuel mixture.

Muffler Replacements

At Morningstar Auto Parts we know that when your engine runs and pushes exhaust through the exhaust pipe it is unbearably loud. Your muffler dampens or shapes the sound produced by your engine and exhaust pipe. Different types of mufflers produce different sounds ranging from extremely quiet to an ear-splitting roar. So whether you are looking to make your vehicle as quiet as possible, or one that announces your arrival, at Morningstar Auto Parts, we have a performance muffler for you.
