      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.

      Auto Parts: Dealer vs. Aftermarket
      The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.
