Overview

Air/Fuel Ratio Sensors utilize a sophisticated sensing element that enables them to produce a precise output in proportion to the air/fuel ratio. AFR sensors provide the ECU with an exact AFR response, resulting in better performance, lower emissions, and increased gas mileage. Denso oxygen sensors feature an aluminum-oxide trap layer to protect the ceramic from silicone and lead poisoning, preventing damage to the platinum electrode. Double protection cover maintains proper unit temperature for quicker response times and protects the ceramic element from contamination. Stainless steel housing resists corrosion and contamination with a rugged, watertight body. Porous PTFE filter allows atmospheric oxygen the enter the sensor without permitting water or engine contaminants to seep into the casing.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.
