GPD 1815156 Downstream Nitrogen Oxide NOx Sensor Direct Fit

The GPD 1815156 is a direct-fit downstream Nitrogen Oxide (NOx) sensor designed as a factory-specification replacement for compatible North American vehicles. NOx sensors are a critical component of modern emissions control systems, monitoring nitrogen oxide levels in the exhaust stream to help the engine management system regulate the Selective Catalytic Reduction (SCR) system and maintain compliance with emissions standards.

Key Features:

• Direct Fit – Engineered as a drop-in replacement for OEM-equivalent fitment with no modifications required
• Downstream Position – Monitors exhaust gases after the catalytic converter for precise emissions feedback
• 5-Wire Design – Features a 5-terminal, blade-style connector with an oblong connector housing for secure, reliable connection
• Factory Specifications – Constructed to meet OE material and performance standards
• North America Fitment – Designed specifically for North American market vehicles
• Quantity – Sold individually (1 sensor per pack)
