Welcome to the HQPASFY Oxygen Sensors category, your go-to source for reliable replacement O2 sensors designed specifically for popular Ford and GM vehicles. With just two curated products—a 2-piece upstream and downstream set for the 2014-2020 Ford Fusion Turbocharged 1.5L L4, and a 4-piece set for 2012-2017 Chevrolet Caprice, Traverse, GMC Acadia, Cadillac XTS, and Buick Enclave V6 3.6L—these sensors deliver precise air-fuel ratio monitoring to restore engine efficiency, reduce emissions, and trigger fewer check engine lights.
Understanding Oxygen Sensors and Their Importance
Oxygen sensors, or O2 sensors, are critical components in modern vehicles, located in the exhaust system to measure oxygen levels in exhaust gases. They send real-time data to the engine control unit (ECU), enabling adjustments to the fuel mixture for optimal combustion. Faulty sensors lead to poor fuel economy, increased emissions, rough idling, and failed smog tests. Replacing them with quality parts like those from HQPASFY ensures your vehicle runs smoothly and passes inspections effortlessly.
In the broader world of automotive maintenance, these sensors fall under essential Replacement Parts. If you're troubleshooting sensor issues, exploring the full range of Sensors can provide additional options for your repair needs.

Featured HQPASFY Oxygen Sensor Kits
We carry two tailored kits to match your vehicle's needs:
- 234-5172 & 234-8039 (2-Piece Set): Perfect for the Ford Fusion Turbocharged 1.5L L4 (2014-2020). This upstream and downstream pair monitors pre- and post-catalytic converter performance, ideal for turbo models prone to sensor fouling from rich fuel mixtures.
- 234-4566 & 234-4565 (4-Piece Set): Comprehensive coverage for GM's V6 3.6L lineup, including Chevrolet Caprice/Traverse (2012-2017), GMC Acadia, Cadillac XTS, and Buick Enclave. With two upstream and two downstream sensors, it's suited for vehicles with dual-bank exhaust systems.
Choosing between them is straightforward: opt for the Ford-specific 2-pack if you drive a Fusion, or the GM 4-pack for crossovers and sedans with more sensors. Both kits use threaded bodies for secure mounting and OEM connectors for hassle-free swaps.
Key Features and Buying Considerations
When shopping for oxygen sensors, prioritize these HQPASFY highlights:
- OE Direct Fit: Matches factory specs for seamless integration—no cutting or splicing wires.
- Wideband Compatibility: Handles lean-burn and stoichiometric mixtures in modern ECUs.
- Extended Lifespan: Rated for 60,000+ miles, resisting contamination from oil or coolant leaks.
- Easy Installation: Typically a 30-60 minute DIY job with basic tools; use anti-seize on threads for longevity.
Verify your vehicle's year, engine size, and sensor positions (upstream before cat, downstream after) using your VIN or service manual. For alternatives, consider established names like those in Denso Oxygen Sensors or Bosch Automotive Oxygen Sensors categories if HQPASFY stock is low.
