OXYGEN SENSORS

A car’s oxygen sensor is constantly exposed to a barrage of harmful contaminants that can rob it of its ability to produce an efficient reading. Engine lubricants, sealants and additives, silicone, and/or oil can damage a sensor’s element.

Our DENSO First Time Fit® oxygen sensors are coated with a special formulation of aluminum oxide to trap impurities outside of the ceramic element. In head-to-head testing against the leading competitors, DENSO oxygen sensors were rated two times more resistant to silicone and lead poisoning.

DENSO oxygen sensors are specifically designed to meet the increasing demands of today’s engines. Each of our oxygen sensors is constructed of the highest quality materials available. High-quality stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminum oxide, high-grade platinum and ceramics are used in each DENSO sensor.

Bottom Line: DENSO produces the finest oxygen sensors in the world. How can we state this? Because, in many cases, Denso has designed, tested, and manufactured the OE unit.

Our Denso Oxygen Sensors will prove to be the best O2 Sensor you can install in your Subaru.

Features:

• SUPERIOR DESIGN — Maximizes engine performance and fuel efficiency while reducing harmful emissions.
• DOUBLE-PROTECTION COVER — Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
• ALUMINUM-OXIDE TRAP LAYER — Keeps silicone and lead outside the ceramic element through DENSO’s exclusive design, preventing damage to the platinum electrode.
• STAINLESS STEEL HOUSING — Resists corrosion and contamination with a rugged, watertight body.
• POROUS PTFE FILTER — Allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing.
