Likala O2 Oxygen Sensor Kit for Chevy Silverado 1500 2008-2012 — Upstream & Downstream, OEM Fitment

Likala O2 oxygen sensors (upstream and downstream) replace worn sensors on compatible GM trucks and SUVs to restore accurate air-fuel monitoring and smoother engine performance.

If your Silverado, Sierra, Tahoe, Yukon or Escalade from the 2008–2014 model years is showing a check engine light, reduced fuel economy or rough idle, the oxygen sensors may be the root cause. Likala supplies upstream and downstream sensors engineered to match factory fitment and electrical connections for many GM V8 and V6 engines. These sensors use heat-resistant materials, pre-coated threads for easier installation and calibrated response characteristics to re-establish proper closed-loop fuel control.

Will these sensors fit my Chevy Silverado or GMC Sierra?

Likala lists compatibility across many GM models and engine sizes from 2008 through 2014. Compatibility depends on engine displacement and whether your vehicle uses upstream (pre-catalytic) or downstream (post-catalytic) sensor locations. Always confirm your vehicle’s year, engine code and OEM part numbers against the replacements below before ordering.

• Direct fit for Silverado 1500 with 4.8L, 5.3L, 6.0L (2008–2012).
• Fitment also includes HD 2500/3500 6.0L, Tahoe, Suburban, Yukon and select Escalade models; see full model list in product details.
• Cross-references many OEM part numbers such as 12569429, 12573005, 234-4256 and others for verification.

How do Likala sensors improve drivability and efficiency?

A failing oxygen sensor gives incorrect oxygen readings to the engine control unit, which can cause rich or lean fuel trims and affect drivability. Replacing both upstream and downstream sensors with properly functioning units restores correct feedback to the ECU, helping the engine maintain optimal fuel mixture and smoother performance.

• Faster sensor response reduces lag in closed-loop fuel corrections.
• Stable readings help preserve catalytic converter efficiency.
• Durable materials maintain reliable operation at high exhaust temperatures.

What are the technical features and installation notes?

Each Likala O2 sensor is built from materials selected for high-temperature endurance and long service life. Sensors arrive with threads pre-coated to simplify hand installation and reduce the risk of seizing. Wiring harnesses and connector types are manufactured to match factory electrical interfaces for plug-and-play replacement in most applications.

• High-temp construction and protective sensing element for longevity.
• Pre-coated threads for smoother installation and future removal.
• OEM-style connectors and lead lengths to match vehicle harness routing.

Which part numbers do these Likala sensors replace?

The Likala set replaces a broad range of OEM references so you can confirm compatibility with your current part number. Cross-reference your vehicle’s existing sensor numbers or service manual to ensure the correct upstream/downstream positions are selected before purchase.

• Replaces popular OEM numbers: 234-4256, 213-3866, 12573167, 12576131 and many others.
• Suitable for both upstream (before catalytic converter) and downstream (after converter) locations as listed.
• See the detailed vehicle and part list in the product description for exact matches.

Who is this for: This Likala O2 sensor pair is aimed at owners and independent mechanics who need a cost-effective, quality replacement for failed oxygen sensors on compatible GM trucks and SUVs. It’s appropriate for anyone comfortable verifying fitment using engine size and OEM part numbers, and for installers seeking sensors with durable construction and straightforward plug-in compatibility. If you run a repair shop or perform your own maintenance and need to restore accurate exhaust oxygen sensing and fuel management, these Likala sensors are a practical replacement option. If you’re unsure about compatibility, check your vehicle’s existing sensor part number or contact the seller for fitment confirmation before buying.
