The HigherBro 4x Oxygen O2 Sensor Kit is designed to monitor exhaust composition across a wide range of 2008–2013 GM models, including Chevy Silverado 1500, Tahoe, Suburban, Avalanche, and GMC Sierra/Yukon families. This package provides four oxygen sensors arranged as two upstream and two downstream units. Crafted with aluminum oxide construction and a flange-mount design, these sensors are built for straightforward installation. They run on a 12-volt supply and output an analog voltage signal that integrates with your vehicle’s engine management system without requiring special adapters.

Key features at a glance

  • Four sensors included: 2 upstream, 2 downstream
  • Aluminum oxide sensors with flange mount for durable, easy fit
  • Measuring range 0 to 20.5% with analog voltage output
  • 12-volt compatibility designed for a broad GM vehicle range
  • One-year quality guarantee for purchase confidence

What you may notice in everyday driving

On many GM pickups and SUVs, these sensors provide real-time feedback on the exhaust stream and air-fuel balance. Upstream sensors watch the mixture entering the engine, while downstream sensors help validate catalytic converter performance. Realistic expectations: improvements depend on the vehicle’s condition and proper installation.

Materials, durability, and reliability

Built from high-quality aluminum oxide and designed for a flange-mount fit, the sensors aim for robust performance under typical under-hood conditions. The 12-volt operation aligns with common automotive sensor standards, which may support consistent signal output over time.

Installation and compatibility

  • Includes four sensors total (2 upstream, 2 downstream)
  • Flange-mount design simplifies mounting and alignment
  • Before buying, verify fit by using the Select Your Vehicle option to match your Make, Model, Year, and Engine

Note: Always check the product page for compatibility with your exact vehicle configuration before purchase to ensure an optimal fit for your engine setup.
