BLPextrm Oxygen O2 Sensor – Upstream & Downstream Fits 2006-07 Chevy/GMC (4PCS)

Overview

The BLPextrm Oxygen O2 Sensor set is built to cover both upstream and downstream positions across a broad lineup of GM vehicles from 2006 to 2007. This 4‑piece kit is designed for popular Chevrolet, GMC, and Cadillac models, offering a straightforward replacement path when sensors begin to wear or show signs of aging. Rather than a single part, you get a complete set intended to restore traditional engine monitoring workflows and support steady engine management in daily driving.

Why this set stands out

Each sensor is crafted with careful material selection and engineering to perform reliably in the demanding environment of a modern engine bay. The sensors are built to endure heat and vibration, with a design that supports faster response times and a longer potential lifespan compared with older equivalents. The result is a sensor kit that aims to help you maintain consistent air-fuel sensing, which plays a key role in how the engine runs under various loads and temperatures.

Compatibility and fitment

• Application: Upstream and downstream sensors designed for GM vehicles such as Chevy Avalanche, Silverado, Suburban, Tahoe, and GMC Sierra, Yukon, and more from the 2006–2007 window.
• Replacement part numbers: The kit maps to a broad range of OE and cross-reference numbers to assist with compatibility verification.
• Before purchasing: Please carefully check your vehicle year, brand, model, plug type, and part number to confirm fitment.

Performance and reliability

• Engine monitoring: The sensors aid in maintaining the air-fuel balance and enable ongoing engine monitoring for smoother operation.
• Drivability: When sensors function properly, you may notice steadier idle and more responsive acceleration in everyday driving.
• Durability: Robust construction is designed to stand up to engine heat and vibration over time.
