An international automobile company founded in Japan, Mazda is now one of the leading Japanese automakers whose vehicles are successfully sold and used globally. The corporation was established almost 100 years ago, and its major production line consists of automobiles, compact and light trucks, and engines.

The components are aftermarket, developed by reliable and well-known manufacturers such as Denso, Dorman, Spectra Premium, Genuine, Standard, Bosch, Beck Arnley, and many others. The products are grouped by Mazda models, and if you need to find the necessary part for your Mazda in a couple of minutes, just sort out the components by type, brand, or price. To give you a good overview of each product and make your decision easier, we have added useful information to product pages – product descriptions, specifications, images, and customers’ reviews can be found there.

      Oxygen Sensors - Why Does My Car Have Four, And Can I Replace One Myself?
      An oxygen sensor (also known as an O2 sensor or Lambda sensor) is a sensor designed to generate a reading based on the content of oxygen in an automotive exhaust system. The sensor itself is made of a ceramic compound with porous-shaped electrodes coated in platinum, surrounded by a protective metal shell casing. O2 sensor casings are threaded, and the entire unit is designed to screw in until it reaches a half-in, half-out position on the exhaust pipe. Modern oxygen sensors are heated to ensure they reach operating temperature quickly.
