Overview

Nifeida 234-4668 upstream O2 sensor is designed as a direct replacement for a broad range of GM vehicles from 2003 through 2014. It measures the oxygen level in exhaust gas and feeds data to the engine control unit to support balanced fuel delivery and smooth combustion. Built with attention to fit and function, this sensor aims to help your vehicle maintain accurate monitoring as part of regular maintenance.

Crafted to align with OE expectations, the sensor is designed to be cross-referenced with multiple OE numbers. This makes it easier to confirm compatibility before purchase and ensures a reliable substitute when the original part needs replacement.

  • Vehicle coverage spans 2003–2014 Tahoe, Suburban, Avalanche, Silverado; also fitment for Yukon XL, Isuzu Ascender, GMC Sierra HD, Envoy, Cadillac Escalade, Buick LaCrosse, Pontiac and Saturn variants, among others.

Durable construction and installation ease

  • Made with high-quality stainless steel and durable materials designed to withstand engine bay heat and road vibrations.
  • Designed as a direct replacement in the original sensor position, with pre-coated threads to aid installation and reduce cross-threading risk.
  • Cross-reference capable with a wide range of OE numbers, so substitution is straightforward when the model matches.
