Description

This Denso 234-9305 Air/Fuel Ratio Sensor is an OE Identical replacement. It features a sophisticated sensing element for precise air/fuel ratio output, contributing to better engine performance, reduced emissions, and improved gas mileage. The sensor is designed with an aluminum-oxide trap layer to protect the ceramic element from silicone and lead poisoning, and a double protection cover to maintain optimal temperature for quick response times and prevent contamination. Its rugged, watertight stainless steel housing resists corrosion, while a porous PTFE filter allows atmospheric oxygen to enter without contaminants.
