higherbro Oxygen O2 Sensor Pair (Sensor 1 & 2) for Chrysler/Dodge/Jeep — Matched Upstream & Downstream Set

higherbro 2PCS Oxygen O2 Sensor 1 & 2 is a replacement upstream and downstream oxygen sensor pair engineered to restore accurate air/fuel monitoring on compatible Chrysler, Dodge, Plymouth and Jeep vehicles.

These two O2 sensors are sold as a matched set (sensor 1 and sensor 2) to replace worn or failing sensors that can trigger check-engine lights, affect fuel trim, or reduce emissions control performance. Manufactured to meet common OE fitment specs, the pair includes connectors and wiring length appropriate for the listed vehicle applications. Before ordering, confirm your exact make, model, year and engine in the vehicle selector to ensure compatibility.

Will these sensors fit my vehicle?

Compatibility depends on your model year and engine size. This kit fits many late-1990s Chrysler, Dodge, Plymouth and Jeep vehicles with the listed engines; confirm with the site’s “Select Your Vehicle” tool.

• Fits upstream (bank 1) and downstream (bank 1) positions for compatible models
• Common fits include Jeep Wrangler 1997–1999 (4.0L) and Dodge Dakota 1997–2000 (various engines)
• Also listed for Chrysler Cirrus, Plymouth Breeze, Dodge Ram/Stratus/Chassis variants
• Double-check engine displacement and year before purchase

How do these sensors affect engine performance?

Oxygen sensors feed exhaust oxygen measurements to the engine control module, which adjusts fuel delivery. Replacing aged sensors with this matched pair helps the ECU make more accurate trims, which can improve drivability and emissions behavior.

• Restores accurate air/fuel feedback to the ECU for better fuel trim
• Helps clear OBD-II codes related to O2 sensor circuit or efficiency when faulty sensors are replaced
• Both upstream and downstream sensors ensure coordinated readings across the exhaust system

What comes with the kit and what should I check before installation?

The package includes two oxygen sensors (upstream and downstream). Before installing, inspect connector type, wiring length and sensor threads to match your vehicle’s harness and mounting boss.

• Includes two sensors (Sensor 1 and Sensor 2) ready for direct replacement where specified
• Verify connector style and wiring routing against the original sensors
• Keep an OBD-II scanner handy to reset or monitor system readiness after replacement

Who is this for? This higherbro O2 sensor pair is intended for DIY mechanics, independent shops and fleet owners who need a cost-effective, matched upstream/downstream replacement for late-1990s Chrysler, Dodge, Plymouth and Jeep models. If your vehicle shows O2-related diagnostic trouble codes, poor fuel economy, or failed emissions tests, and it matches the listed years/engines, this kit provides a straightforward repair option. Remember to use the vehicle selector before purchase and take advantage of the included 1-year unlimited mileage quality guarantee for added confidence.
