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.

      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.
