Product Description
Restore your vehicle's emissions system performance with this OEM-specification NOx sensor. Manufactured by Continental (Vitesco Technologies) — the original supplier to Volkswagen Group — this sensor measures nitrogen oxide levels in the exhaust before the catalytic converter to ensure proper EGR valve operation, SCR system function, and optimal fuel efficiency.
