BLPextrm O2 Oxygen Sensor Upstream/Downstream Kit for GM Trucks

Under the hood, a precise oxygen sensor helps the engine breathe and behave predictably. The BLPextrm O2 Sensor Upstream/Downstream kit is designed as a direct fit for a range of 2006 and 2007 GM models, including Chevy Avalanche, Silverado 1500, Suburban and GMC Sierra Yukon families. This kit consolidates upstream and downstream sensors to support balanced exhaust monitoring, contributing to steadier idling and smoother acceleration in daily driving scenarios.
