O2 Oxygen Sensor Upstream Downstream for Dodge Charger (2006-2014) 2.7L, 3.5L, 3.6L, 5.7L, 6.1L, 6.4L

Direct-Fit Oxygen Sensor Set for 2006-2014 Dodge Charger (LX / LD)

What it Does: The 4-piece direct-fit oxygen sensor set replaces degraded pre- and post-catalyst sensors on the 2006-2014 Dodge Charger to restore precise closed-loop air-fuel metering, engine efficiency, and emissions compliance.

The Stock Dodge Charger Sensor Contamination & Thermal Degradation

Factory oxygen sensors on the LX and LD platform operate under extreme exhaust thermal cycles. Over time, the internal zirconia ceramic sensing elements degrade due to unburned carbon deposits, oil blow-by, and silicates. Worn upstream sensors develop lazy switching speeds that skew short-term and long-term fuel trims (STFT/LTFT), causing rough idle, hesitation under load, poor fuel mileage, and engine misfire codes. Simultaneously, fatigued downstream sensors generate erroneous catalytic converter efficiency trouble codes such as P0420, P0430, or circuit DTCs like P0130 through P0161.

The Engineering Solution

This comprehensive 4-sensor pack supplies two upstream and two downstream sensors engineered with precision planar ceramic elements and fast-acting integrated heaters. Built with laser-welded stainless steel housings and dual protective thermal covers, these sensors resist soot accumulation and thermal shock. Pre-calibrated factory-length harness pigtails and OE-spec multi-pin weatherproof connectors plug directly into the engine harness without splicing, while precision M18 threads ensure a leak-free seal in standard exhaust bungs.

Frequently Asked Questions & Fitment Warnings

Does this fit the LX / LD Charger?

Yes, this is a direct fit for 2006-2014 Dodge Charger models equipped with the 2.7L, 3.5L, 3.6L Pentastar, 5.7L HEMI, 6.1L HEMI, and 6.4L 392 HEMI engines. Always verify harness length and pin configuration prior to final mounting.

Do I need to reset the ECU fuel trims after installing these sensors?

Yes, clearing active diagnostic trouble codes and performing a battery or PCM reset allows the engine computer to immediately relearn baseline stoichiometric air-fuel tables with the new sensor data.

The Dodge Muscle Standard

Maintaining responsive, balanced fuel delivery is essential for maximizing wide-open-throttle torque and crisp throttle response across the Charger's high-output V6 and HEMI powertrains.
