NGK Cadillac Allante 1993 Direct Fit Oxygen Sensor

This NGK oxygen sensor is what you get when you need to replace the one on your 1993-1995 Cadillac Eldorado, DeVille, Seville, or 1995 Oldsmobile Aurora. It's a direct fit replacement designed to work with your vehicle's onboard diagnostic system. Oxygen sensors are key players in keeping your engine running smoothly, helping to maximize your fuel efficiency and cut down on harmful emissions. They constantly send information back to your car's computer, the ECU, to help manage the air-fuel mixture and alert you if there's an issue with the fuel system or the catalytic converter.

NGK, a major supplier of original equipment oxygen sensors, builds these with an advanced ceramic sensor element. This element features a special overcoat designed to resist contamination and protect against poisoning, which can happen over time from exhaust gases and deposits. This focus on the ceramic element, from raw materials to the finished product, is what NTK specializes in, aiming to improve sensor performance and resistance to failure.
