Save 50-70% vs. Dealer Pricing Get OE-quality performance without the OE markup. Most dealer NOx sensors cost $400-$800+; ours deliver the same function at a fraction of the cost. Fleet-Tested Reliability Our sensors are trusted by independent repair shops and fleet operators across North America for daily-use diesel vehicles. Fast Shipping from US Stock Orders ship within 1 business day. No 2-4 week backorder delays common with dealer parts. No Core Charge Unlike dealer replacement programs, there's no core deposit or return requirement. Installation Tips Safety First: Allow exhaust system to cool completely before beginning (NOx sensors reach 600 C+ during operation). Locate the Sensor: Find the sensor on the exhaust pipe near the SCR catalyst. Refer to vehicle service manual for exact location. Unplug & Remove: Disconnect the electrical connector, then use a 22mm or 7/8" oxygen sensor socket to unscrew the old sensor. Install New Sensor: Thread the new sensor by hand first to avoid cross-threading. Torque to 35-45 Nm (26-33 ft-lbs). Anti-seize is pre-applied on threads. Connect & Clear Codes: Plug in the electrical connector until it clicks. Use OBD-II scanner to clear any stored NOx-related fault codes. Test Drive: Complete 1-2 drive cycles for the ECU to complete sensor readiness monitors. Frequently Asked Questions Q: What is a NOx sensor and why does it fail? A: A NOx (Nitrogen Oxide) sensor monitors the nitrogen oxide levels in your diesel engine's exhaust system, feeding data to the ECU for SCR/DPF regeneration. Common failure causes include soot contamination, thermal cycling fatigue, and sensor element degradation over 100,000+ miles. Symptoms of failure include Check Engine Light (CEL), poor fuel economy, failed emissions test, and derate mode. Q: Is this 5WK9
