BLPextrm O2 Oxygen Sensor Set for Chevy Silverado Suburban 2006–2007 — Upstream & Downstream, High-Temp Durable

BLPextrm O2 Oxygen Sensor set for upstream and downstream positions restores reliable air-fuel sensing in compatible 2006–2007 GM trucks and SUVs.

This replacement oxygen sensor assembly from BLPextrm is engineered to match fitment and function for a wide range of Chevrolet and GMC vehicles from model years around 2006–2007. Designed to withstand high exhaust temperatures and respond quickly to changing oxygen levels, it helps the engine control unit maintain correct fuel trim and emissions monitoring. Before ordering, confirm your vehicle year, engine displacement, and connector or part number to ensure the correct sensor for upstream or downstream locations.

Which trucks and SUVs does this oxygen sensor fit?

The BLPextrm sensor covers upstream and downstream applications for many Chevy and GMC models from the 2006–2007 era. Fitment includes Silverado, Sierra, Avalanche, Suburban, Yukon, and Yukon XL with the common engine displacements used in those years. Always cross-check with your vehicle VIN or existing sensor part number to avoid mismatch.

• Chevrolet: Avalanche, Silverado 1500, Silverado 1500 Classic, Suburban 1500/2500 (2007)
• GMC: Sierra 1500 (2006–2007), Sierra Classic body style (2007), Yukon and Yukon XL 2006–2007
• Engine sizes commonly covered include 4.3L, 4.8L, 5.3L, 6.0L and 6.2L variations

How does this oxygen sensor compare in durability and performance?

BLPextrm sensors are built from high-temperature materials and optimized for fast response to changing exhaust gas composition. They are rated for continuous operation at elevated temperatures, which supports long service life and consistent voltage signals to the engine control module. Durable construction reduces the chance of early failure from heat or contamination.

• Materials rated for sustained use at temperatures up to 650°C
• Faster response time to provide accurate air-fuel feedback
• Designed to minimize premature wear and maintain signal stability

What replacement part numbers and connectors are compatible?

This product replaces many OEM and aftermarket O2 sensor numbers used on GM vehicles of this era. Compatibility covers a broad list of legacy part numbers and cross-references; however, the correct choice depends on your vehicle’s original sensor position and harness connector. Verify the part number stamped on the old sensor or consult your service manual before purchasing.

• Cross-references a wide range of GM and aftermarket numbers for upstream/downstream locations
• Matches common connector styles used on 2006–2007 Chevy and GMC models
• Always confirm plug type and part reference to avoid installation issues

How do I handle installation and post-install checks?

Installation typically requires basic hand tools and access under the vehicle or at the exhaust manifold. Use anti-seize only as directed and avoid damaging the sensor tip or wiring. After installation, clear any stored diagnostic trouble codes and allow the vehicle to complete a drive cycle to confirm the ECU is receiving stable oxygen readings.

• Use appropriate O2 sensor socket or crowfoot wrench to avoid damage
• Do not contaminate the sensing element with grease, silicone, or cleaners
• Clear fault codes and verify normal closed-loop operation after replacement

Who is this for: This BLPextrm oxygen sensor set is intended for DIY mechanics, independent repair shops, and vehicle owners restoring proper air-fuel sensing on compatible 2006–2007 Chevrolet and GMC trucks and SUVs. If you need a durable aftermarket sensor that mirrors OEM fit and function, and you can confirm fitment by year, engine size, and connector type, this product provides a cost-effective replacement option. If you are unsure about compatibility, gather your vehicle information or the existing sensor’s part number and contact the seller for guidance before ordering.
