This DENSO oxygen sensor is a direct-fit, heated, 4-wire replacement part. It is built to OE standards and made for an exact fit. The wire length is 12.68.
The housing is laser-welded stainless steel that resists corrosion. A PTFE filter blocks contaminants under harsh engine conditions. Dual-layer protection shields the ceramic element to support fast, reliable response times.
An aluminum oxide trap layer protects the ceramic element from silicone and lead poisoning.
