Denso First Time Fit Oxygen Sensor

Denso First Time Fit oxygen sensors are 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.

Features and Benefits:

• 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.

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.

Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Please confirm the correct part before ordering and if the connector does not match, do not install.

Recommended Installation Tool - 234-0100, O2 Sensor Socket Set
