4-wire 58x Gen 4 LS O2 Sensor for Air-Fuel Ratio Measurement
Tracking real-time oxygen levels in a Gen 4 LS swap demands a sensor that matches the factory reluctor ring and delivers precise feedback under all driving conditions. This 4-wire O2 Sensor - 58x Gen 4 aligns with the 58 tooth wheel and plugs directly into the stock harness to eliminate adapter wiring and potential signal noise. By isolating heater and measurement circuits the sensor reaches operating temperature quickly without compromising accuracy so it provides stable data from cold idle through wide open throttle. Stainless steel housing and a ceramic core withstand extreme exhaust heat and vibration for consistent closed loop control and reliable engine management on road and track.
Four-Wire Architecture for Fast Warmup and Stable Oxygen Readings
The four-wire design separates the heater circuit from the sensing element to bring the core up to operating temperature in seconds. By investing heat early, the sensor provides accurate oxygen readings almost immediately after engine start. This prevents rich or lean excursions during the critical warmup phase, protecting catalytic components and smoothing out idle behavior. Isolating the heater supply also means measurement voltages remain unaffected by current draw, so the ECU receives a clean, stable signal under sudden throttle changes or rapid load shifts.
Exact Fit for Gen 4 LS 58-Tooth Reluctor Ring
This O2 sensor is engineered to match the Gen 4 LS crankshaft's 58-tooth pattern without any adapter harness. A square four-pin connector plugs directly into the factory wiring loom, eliminating splices that could introduce signal noise or trigger fault codes. The direct fit approach reduces installation time and wiring complexity, allowing builders to focus on mechanical integration. Precise alignment with the reluctor ring ensures the ECU sees correct timing and mixture data, which is vital for reliable ignition control and emissions compliance.
Stainless Steel Housing and Ceramic Core for Lasting Durability
A robust stainless steel housing shields the sensing element from corrosive exhaust gases and repeated heat cycles common in swap applications. Inside, the advanced ceramic core maintains calibration and resists deformation under intense vibration. This material pairing prevents premature wear that can cause signal drift, so oxygen feedback stays consistent through spirited street runs or extended track sessions. The result is a sensor that withstands thermal shock without compromising accuracy over thousands of miles.
Real-Time Oxygen Data Enabling Optimal Combustion Control
Accurate, real-time oxygen measurements are the foundation of precise air-fuel ratio management. This sensor feeds the ECU the exact voltage signals needed to fine-tune injector timing and fuel delivery on the fly. As a result, combustion efficiency improves, fuel economy rises, and unwanted emissions are reduced. Drivers benefit from smooth throttle response and predictable power delivery, while tuners gain confidence that closed loop corrections are based on reliable, worry-free data.
