58x Gen4 4-Wire O2 Sensor Optimized for LS Engines

Accurate oxygen data from the 4-wire architecture keeps your LS engine calibrated for precise air fuel control across any RPM range and throttle positions, supporting aggressive tuning. Built for direct fit with Gen4 heads and 58x reluctor rings, the square 4 pin connector enables plug and play installation to reduce setup time and errors, and the stainless steel housing tolerates high heat to deliver consistent power, improved economy and lower emissions.

4-wire 58x Gen 4 O2 Sensor for LS Engine Swaps

For builders tackling an LS engine swap with Gen 4 electronics, the 4-wire O2 Sensor - 58x Gen 4 takes the guesswork out of air fuel monitoring by matching the factory 58 tooth crank reluctor pattern. Its square plug aligns directly with the stock harness and eliminates any need for adapter wiring or signal corrections. Additionally the stainless steel housing and ceramic sensing element resist extreme exhaust temperatures and vibration so readings stay consistent under load. By separating heater and measurement circuits this sensor delivers precise oxygen feedback from cold start through full operating temperature.

Four Wire Sensor Design for Fast Heat Up and Accurate Oxygen Feedback

The four wire architecture separates the heater circuit from the measurement element, allowing the sensor to reach operating temperature more quickly without compromising data integrity. Early warm up is critical for achieving stable voltage readings immediately after engine start, preventing lean or rich spikes that can affect catalytic converter life. By isolating the heater element, the engine control unit receives consistent oxygen feedback across a broad temperature range, improving closed loop tuning precision. Under sudden throttle changes the independent circuits maintain continuous signal flow so air fuel ratios stay on target. This design ultimately supports more reliable engine performance and more predictable fuel economy.

Direct Fit Compatibility with Gen 4 LS 58 Tooth Reluctor Rings

Engineers crafted this sensor to align exactly with the 58 tooth crank reluctor pattern found on Gen 4 LS engine controllers, removing the need for adapters or custom wiring splices. The square four pin connector matches the factory crank position harness, eliminating harness modifications that can introduce signal errors or trigger fault codes. This direct fit approach ensures correct timing data is sent to the ECU, safeguarding ignition accuracy under all driving conditions. Builders save installation time and avoid troubleshooting wiring issues, resulting in a cleaner engine bay and a smoother swap process.

Stainless Steel Housing Protects Against Heat and Vibration

The sensor's stainless steel shell provides exceptional resistance to corrosive exhaust gases and repeated thermal cycling in high temperature environments. Inside, a robust ceramic sensing element remains insulated from engine bay vibration, preserving calibration over thousands of operating hours. This rugged construction prevents degradation of the sensing surface, so oxygen readings stay consistent even under heavy load or track use. Durability of both housing and element is essential for long term emissions compliance and stable tuning. As a result, tuners can rely on uninterrupted performance without frequent sensor replacement.

Engineered for a reliable fit and precise oxygen readings throughout your LS swap.
