A-tnewb Mini Cooper O2 Sensor Pair — 2007-2010 1.6L Upstream & Downstream Direct-Fit, OEM-Style Replacement

A-tnewb 2PCS Oxygen O2 Sensor is a direct-fit upstream and downstream replacement for 2007–2010 Mini Cooper 1.6L engines, restoring accurate exhaust oxygen readings and helping the engine manage fuel trim.

These two oxygen sensors from A-tnewb are manufactured to match OEM fitment and wiring for the listed 1.6L Mini Cooper models. Sold as a pair (upstream & downstream), they replace part numbers such as 234-5135 and 234-4488 and are intended to integrate with the vehicle's engine control system to supply reliable exhaust oxygen data.

How will these sensors affect my Mini Cooper's performance?

Replacing failing O2 sensors helps the engine computer maintain correct air-fuel ratios, which supports smoother running and better fuel efficiency. While sensors do not increase engine power, they prevent poor combustion caused by inaccurate oxygen readings.

• Restores correct oxygen feedback to the ECU
• Improves fuel-trim accuracy and idle stability
• Reduces risk of rich or lean running conditions

Are these A-tnewb sensors a direct OEM replacement?

Yes. The A-tnewb pair is designed to replace original part numbers like 234-5135, 234-4488, 11787548961, and 17107515499. They match the electrical connectors and mounting dimensions needed for proper installation on compatible Mini Cooper models.

• Direct-fit for 2007–2010 Mini Cooper 1.6L engines
• Compatible with both upstream and downstream locations
• Sold and packaged as a matched two-sensor set

What are the build quality and warranty details?

A-tnewb sensors are built from durable materials intended for long service life and consistent readings under typical driving conditions. Each unit is tested prior to shipping and backed by a one-year unlimited-mileage guarantee for added confidence.

• Quality-tested before shipment
• Durable materials for extended service life
• One-year unlimited-mileage warranty included

How difficult is installation and what should I check?

Installation is straightforward for hobbyists and mechanics familiar with exhaust components: sensors thread into the exhaust manifold or pipe and connect to the factory harness. Always verify connector fitment, torque the sensor to spec, and clear any engine fault codes after replacement.

• Thread-in replacement—no special modification needed
• Verify connector pinout and secure electrical connection
• Use correct torque and clear diagnostic trouble codes after install

Who is this for: The A-tnewb 2PCS O2 Sensor set is aimed at Mini Cooper owners and independent mechanics who need an economical, direct-fit replacement for worn or faulty upstream and downstream oxygen sensors on 2007–2010 1.6L models. Choose this set if you want OEM-compatible connectors, pre-shipment testing, and a one-year warranty to restore accurate exhaust oxygen feedback and reliable engine management.
