• Heated sensor: The heated design supports faster warm-up and more reliable readings during cold start and short trips.
• Fitment: Processed to the original vehicle size for compatibility with Acura ILX 2013-2014 and Honda Civic 2012-2015, offering a straightforward swap without major modifications.
• Connector and wiring: Comes with a male connector and a 4-wire harness (310mm and 330mm lengths) for proper electrical integration and signal transmission.
• Installation aid: Silver alloy melting point joint detail is included to simplify installation and improve mechanical connection.

Who It's For

This sensor suits DIY mechanics and independent repair shops replacing a failing O2 sensor on Acura ILX 2013-2014 or compatible Honda Civic model years listed. It is best for owners who prioritize a cost-effective, close-fit replacement that restores emissions feedback and can reduce fuel waste when the original sensor is degraded.

Those who should look elsewhere include drivers who require OEM-branded parts with extended warranty coverage or who need guaranteed long-term performance in extreme environments; some reviewers reported mixed results with upstream sensor longevity, so heavy-duty fleets may prefer a factory or premium aftermarket option.
