Oxygen Sensors for Dodge Challenger (2009-2023) 5.7L Upstream & Downstream

Direct-Fit Oxygen Sensor Replacement Set for 2009-2023 Dodge Challenger (LC / LA)

What it Does: The Oxygen Sensor Set replaces worn or fouled factory exhaust sensors on the 2009-2023 Dodge Challenger 5.7L to restore precise closed-loop air-fuel metering and clear catalytic efficiency diagnostic codes.

The Stock Dodge Challenger Sensor Degradation

With prolonged exposure to high exhaust temperatures, carbon particulate accumulation, and thermal cycling, the factory zirconia sensing elements degrade over time. On the LC / LA platform, sluggish sensor response skews long-term and short-term fuel trims across Bank 1 and Bank 2. This dynamic latency results in unburned fuel, reduced throttle response, poor gas mileage, rough idle hunting, and recurring diagnostic trouble codes such as P0130-P0161, P0420, and P0430.

The Engineering Solution

This comprehensive 4-piece sensor package upgrades both pre- and post-catalytic positions with fast-acting, planar-design sensing elements sealed inside durable stainless-steel housings. Manufactured to exact factory harness lengths and plug-and-play connector profiles, these sensors plug directly into the OEM wiring harness without cutting or repinning. Rapid-activation integrated heating elements reach operational closed-loop temperature quickly, ensuring precise millivolt signal transmission to the powertrain control module (PCM) under heavy throttle.

What's Included

• 2 Upstream Oxygen Sensors (Pre-Catalyst)
• 2 Downstream Oxygen Sensors (Post-Catalyst)

Frequently Asked Questions & Fitment Warnings

Does this fit the LC / LA Challenger?

Yes, this is a direct fit for the 2009-2023 Dodge Challenger equipped with the 5.7L HEMI V8 engine. This set does NOT fit 3.6L Pentastar V6, 6.4L 392 HEMI, or 6.2L Supercharged Hellcat configurations.

Do I need to clear engine codes after installing these sensors?

Yes, clearing the diagnostic fault codes with an OBD-II scan tool is necessary to reset stored fuel trim adaptations and extinguish the check engine light immediately.
