Pollak 66-001 Diesel Nitrogen Oxide (NOx) Sensor – Precision Aftertreatment Component

Restore Emissions Efficiency and Engine Performance
Maintain your vehicle's compliance and fuel efficiency with the Pollak 66-001 Diesel NOx Sensor. This critical component is engineered to monitor the nitrogen oxide levels in your diesel engine's exhaust stream, providing real-time data to the Engine Control Unit (ECU). By ensuring the Selective Catalytic Reduction (SCR) system is functioning at peak efficiency, this sensor helps prevent "limp mode" and keeps your truck on the road.

OEM-Quality Precision and Durability
Built to meet or exceed rigorous industry standards, the Pollak 66-001 is designed for the harsh, high-vibration environment of diesel exhaust systems. It features high-grade ceramic sensing elements and corrosion-resistant housing to withstand extreme temperatures and chemical exposure. Whether you're managing a commercial fleet or maintaining a single heavy-duty truck, this sensor offers a reliable, cost-effective alternative to expensive dealership parts.

Direct-Fit Engineering
Designed as a direct-fit replacement, the 66-001 ensures a seamless installation process with no modifications required. Accurate sensing reduces excessive Diesel Exhaust Fluid (DEF) consumption and prevents the premature clogging of the Diesel Particulate Filter (DPF), extending the life of your entire aftertreatment system.
