higherbro Oxygen O2 Sensor Kit 4PCS for Dodge Grand Caravan — Direct-Replace Upstream & Downstream

higherbro 4PCS Oxygen O2 Sensor kit replaces both upstream and downstream sensors (2x upstream, 2x downstream) to restore accurate air-fuel feedback on compatible Dodge, Chrysler, Jeep and RAM engines.

This four-piece sensor set is engineered as a direct-replacement oxygen sensor kit for a wide range of Chrysler group vehicles, including Dodge Grand Caravan models and many Jeep, Chrysler and RAM applications. Each sensor is built to match OE form, fit and electrical connectors so installation is straightforward for DIY mechanics or professional technicians. The kit comes with a one-year quality guarantee, and we recommend verifying exact vehicle fitment using your vehicle’s make, model, year and engine details before ordering.

Which vehicles and engines will these higherbro oxygen sensors fit?

These sensors cover many Chrysler Group applications across multiple years and engines—both V6 and V8 platforms. They are intended for direct replacement where original-style connectors and mounting threads match your vehicle.

• Common fits: Dodge Grand Caravan 2008–2011 (3.6L, 4.0L variations noted)
• Includes many Jeep Grand Cherokee (3.6L, 5.7L, 6.1L, 6.4L) and Wrangler years
• Covers Chrysler 200, 300 and Town & Country variants across listed years
• Also fits multiple RAM 1500/2500/3500 3.7L, 5.7L and other specified years

How do these sensors help with driving performance and diagnostics?

Oxygen sensors monitor exhaust oxygen content to inform the engine control unit how much fuel to add. Replacing failing sensors helps the vehicle maintain balanced air–fuel ratios, reduces rough running caused by bad inputs, and clears or prevents some diagnostic trouble codes tied to O2 performance.

• Restores accurate oxygen readings to the ECU for correct fueling
• Helps reduce symptoms like rough idle or reduced fuel efficiency tied to bad sensors
• Can resolve OBD-II codes related to sensor circuits or sensor performance

What’s included in the 4PCS kit and what should I check before ordering?

The kit includes four oxygen sensors—two upstream (pre-catalytic converter) and two downstream (post-catalytic converter). Before purchase, confirm your vehicle’s engine size, connector type and sensor locations match the product listing to ensure correct compatibility.

• Contents: 4 sensors (2 upstream, 2 downstream) in higherbro packaging
• Warranty: One year quality guarantee from date of purchase
• Tip: Use the "Select Your Vehicle" tool on the product page to verify fit

How difficult is installation and what tools are typically required?

Installation difficulty ranges from moderate to straightforward depending on sensor accessibility. Many users can complete replacement at home with basic hand tools; some applications may require lifting the vehicle or removing components to reach the sensor.

• Common tools: oxygen sensor socket, ratchet, penetrating oil, torque wrench
• Allow time for cooling exhaust before attempting removal and replacement
• If connectors differ, compare part numbers or consult a technician before installing

Who is this for: This higherbro 4PCS Oxygen O2 Sensor kit is aimed at owners and mechanics who need a full set of upstream and downstream oxygen sensors for Chrysler group vehicles—especially Dodge Grand Caravan drivers—seeking OE-style replacements.
