Denso Upstream Air-Fuel Ratio Sensor with 4-Wire Plug

Denso Air and Gas Ratio sensor is designed to detect the quantity of the exhaust fuel air and gas ratio. It’s constructed from sturdy materials that’s corrosion and abrasion resistant. This sensor options zirconia stable electrolyte built-in with alumina heater substrate which precicely controls the quantity of oxygen focus that flows into the diffusion layer to restrict present circulate. This sensor can simply be put in and ensures longevity.

Our sensors are designed to accurately measure the air-fuel ratio in exhaust gases. Crafted from durable materials and featuring a zirconia stable electrolyte, they offer precise readings and easy installation.
