A Leading Supplier of Reliable O2 Sensors Since 1978

Delphi OE & aftermarket engineers collaborated to develop the most innovative oxygen sensors for the auto industry. Delphi's patented sensor coating offers the best contamination resistance to silicone, phosphorous, and other fuel/oil additives, while planar technology helps reduce emissions. Sensors feature OE connectors and wire lengths for easier installation, better high-temp protection, and reduced vibration damage and wire corrosion to preserve signal accuracy and longevity. Delphi planar O2 sensors replace previous conical sensors to maximize output, and their unique coating provides lifetime operation with E85 and other alcohol-based fuels.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.


WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
