Emissions
When fuel is burned, it leaves behind a gas that has to be safely dispersed into the atmosphere. The parts within the exhaust system take the burned fuel toxins and run them through several components that are designed to reduce the toxins.
The computer on vehicles like your Mazda CX-7 works with sensors to determine how much emissions your engine is producing. The emission system consists of parts like the oxygen sensor, the EVAP, the catalytic convertor and other monitoring and purifying components. All of these components work together to reduce the emissions that are later expelled through the exhaust system.
When a part of this system fails, you may first notice it because your check engine light is on. You may never need to replace any part of the emissions system, but if you do, you want to use an OEM Mazda part because they are exact fit replacement parts. At RealMazdaParts.com, we have emissions system parts with the exact fit you need that will meet factory specifications. Shop online with us now!
