O2 Oxygen Sensor Upstream Downstream for Dodge Magnum (2005-2008) 2.7L, 3.5L, 5.7L, 6.1L

Direct-Fit Oxygen Sensor Set for 2005-2008 Dodge Magnum (LX)

What it Does: The 4-piece oxygen sensor set monitors pre- and post-catalytic exhaust gases on the 2005-2008 Dodge Magnum to restore closed-loop fuel management and resolve diagnostic trouble codes.

The Stock Dodge Magnum Exhaust Sensor Degradation

Over extended thermal cycles, the factory zirconia elements in the LX platform sensors succumb to silica poisoning, oil blow-by contamination, and thermal fatigue. As the internal heating circuits and platinum electrodes degrade, sensor latency increases, locking the PCM into skewed short-term and long-term fuel trims (STFT/LTFT). This sluggish switching speed leads to incomplete combustion, degraded MPG, hesitation under load, and false catalytic converter efficiency codes like P0420, P0430, or circuit faults ranging from P0130 to P0161.

The Engineering Solution

Engineered to exact OEM specifications, this complete 4-sensor array utilizes high-grade, fast-acting planar zirconia ceramic thimbles with integrated internal heaters for rapid light-off times. Stainless steel outer bodies resist exhaust corrosion and thread galling under severe thermal loads. Each sensor features direct-fit weatherproof connectors and heat-shielded wiring harnesses that mount to the stock bungs on both the V6 and HEMI platforms without cutting, splicing, or repinning factory circuits.
