A-Premium Upstream and Downstream O2 Oxygen Sensors 2-Pack — Heated 4-Wire Direct-Fit for 2007–2010 Chrysler/Dodge/Jeep 2.0–2.4L

A-Premium 2-pack upstream and downstream heated O2 oxygen sensors replace factory sensors for compatible 2007–2010 Chrysler, Dodge and Jeep 4-cylinder models.

These two oxygen sensors are designed as direct-fit replacements for the upstream (pre-catalytic converter) and downstream (post-catalytic converter) positions on select Chrysler Sebring, Dodge Avenger, Dodge/Chrysler Caliber, Dodge Journey and Jeep Compass/Patriot vehicles equipped with 2.0L–2.4L inline-four engines from model years 2007–2010. Each sensor is a four-wire, threaded, heated unit packaged in a box and sold as a matched pair so you can restore accurate exhaust oxygen readings and simplify installation without modifying wiring or mounts.

Which vehicles and engine sizes will these sensors fit?

These sensors are intended for several Chrysler Group vehicles with 4-cylinder engines in the 2007–2010 model years. They cover both upstream (B1S1) and downstream (B1S2) positions as specified by the original fitment lists.

• Chrysler Sebring 2007–2010, L4 2.4L
• Dodge Avenger 2008–2010, L4 2.4L
• Dodge/Chrysler Caliber 2007–2010, L4 1.8L / L4 2.0L / L4 2.4L (varies by year)
• Dodge Journey 2009–2010, L4 2.4L
• Jeep Compass/Patriot 2007–2010, L4 2.0L / L4 2.4L

How do these sensors match the original equipment they replace?

Each unit uses a threaded mounting style and a four-conductor, heated sensor design to match OE connectors and performance characteristics. The sensors come with female connectors and overall cable length intended to line up with factory routing for a plug-and-play replacement.

• Reference numbers: 250-24675, 25024675, 56029085AA
• Wire count: 4 (heated sensor configuration)
• Overall cable length: 475 mm for proper reach
• Package includes: 2 oxygen sensors in boxed packaging

What are the installation and durability details I should know?

These sensors are built from durable materials and designed for straightforward installation; basic hand tools are typically all that’s needed to replace the threaded sensor bodies and reconnect the factory plugs. The heated element allows the sensor to reach operating temperature faster, improving early feedback to the engine computer after cold starts.

• Threaded mounting — installs into existing bung or manifold ports
• Heated element for faster warm-up and reliable readings
• No special tools or wiring modifications required for compatible models
• Boxed pair reduces the chance of mismatched sensors when replacing both sides

What warranty and support come with these oxygen sensors?

A-Premium backs these oxygen sensors with a one-year unlimited-mileage guarantee to protect against manufacturing defects, giving you time to confirm fit and function. The brand also supplies multiple automotive accessory categories if you need related replacement parts or tools.

• One-year unlimited-mileage guarantee from A-Premium
• Sold as a pair to ensure matched upstream and downstream performance
• Customer support and parts range from the A-Premium product line

Who is this for: These A-Premium oxygen sensors are intended for DIY mechanics and professional technicians replacing failed or aging O2 sensors on eligible 2007–2010 Chrysler, Dodge and Jeep 4-cylinder vehicles. If you need a direct-fit, heated upstream and downstream sensor pair with OE-style connectors, this kit is a practical, boxed solution backed by a one-year guarantee.
