4-Wire 24x Gen 3 O2 Sensor for Precise Air-Fuel Ratio Monitoring
For builders installing a Gen 3 LS engine, the 4 Wire 24x Gen 3 O2 Sensor delivers reliable oxygen measurements and crank position feedback to support precise tuning. The direct fit to the factory 24 tooth reluctor ring feeds continuous data to the ECU for precise air fuel ratio monitoring under all load conditions. Constructed from stainless steel and a polymer composite, the sensor tip stands up to extreme exhaust heat and vibration. A separate heater and sensing circuit maintain stable operating temperature and consistent voltage readings even during sustained throttle use.
Precision Sync with 24 Tooth Reluctor Ring
By matching the factory 24 tooth reluctor ring on Gen 3 LS engines, this oxygen sensor delivers exact crank position feedback that is critical for timing ignition and fuel injection. The direct engagement with the ring means there is no need for adapters or spacers, eliminating potential sources of error in engine timing. Consistent and precise timing signals help prevent misfires at high RPM and support smooth idling during everyday driving. This level of accuracy lays the foundation for optimal engine performance and reliable ECU control.
Dedicated Four Wire Circuitry for Rapid Warm Up and Accuracy
The separate heater and sensing circuits are a key design feature, allowing the sensor to reach its operating temperature quickly and maintain it under load. A stable sensor temperature produces reliable voltage readings that the ECU uses to fine-tune fuel delivery in real time. This rapid feedback loop sharpens throttle response and maximizes fuel economy by correcting rich or lean conditions instantly. Even during sustained high-load operation, the sensor resists heat soak and continues to provide precise data.
Durable Metal and Polymer Composite Assembly
Constructed with a stainless steel sensing tip and a high-strength polymer composite insulator, this sensor is built to withstand extreme exhaust heat and constant vibration. The corrosion-resistant metal housing protects internal components from harsh conditions, while the composite core absorbs mechanical shock to prevent signal noise. These materials extend service life and reduce the risk of premature failure in demanding swap applications. The result is a sensor that maintains accuracy over many miles without frequent replacement.
Plug and Play Connector for Efficient Installation
The flat 4 pin connector is designed to mate directly with Gen 3 LS harnesses, so there is no cutting or splicing required. Installers simply thread the sensor into the exhaust bung, snap the connector into place, and they are ready to tune. This straightforward procedure reduces installation time and guarantees proper grounding for accurate data transmission. Both professional shops and DIY enthusiasts can complete the upgrade quickly using basic hand tools.
