A-Premium O2 Oxygen Sensor Set for Honda Accord 2008-2012 & Acura TSX 2009-2013 | Upstream & Downstream, 2-PC

Overview

The A-Premium O2 oxygen sensor set is designed for two popular late-2000s to early-2010s vehicles: Honda Accord 2008–2012 2.4L and Acura TSX 2009–2013 2.4L. This package includes both upstream and downstream sensors in a convenient two-piece set, making it easy to refresh your exhaust monitoring with one purchase. Built for durability and straightforward installation, the sensors feature a heated design and a threaded mounting system that matches common OEM fitments. The upstream sensor monitors the engine side of the exhaust before the catalytic converter, while the downstream sensor tracks post-catalyst emissions to help your vehicle’s ECU manage air-fuel balance and emissions monitoring.
