Description

The Denso 234-4574 is an OE-identical oxygen sensor designed for precise exhaust gas measurement. It features a Zirconia sensor with a thimble design and a protective aluminum-oxide trap layer to prevent contamination. This heated, 4-wire sensor is built with stainless steel housing for durability and a porous PTFE filter to allow atmospheric oxygen entry while blocking contaminants.

The sensor's double protection cover helps maintain optimal operating temperature for quicker response times and shields the ceramic element. Denso oxygen sensors meet or exceed original equipment specifications, ensuring reliable performance and proper engine function.
