Gen 4 58x 4-Wire O2 Sensor for LS Engine Air-Fuel Monitoring
When fitting a Gen 4 LS engine, builders need reliable oxygen feedback and the 4-wire O2 Sensor 58x Gen 4 delivers precise air-fuel data without any custom wiring. Its square four pin connector matches the factory crankshaft harness for plug and play installation and prevents fault codes caused by signal errors. Engineers will appreciate that the stainless steel housing and ceramic element resist extreme exhaust temperatures and vibration to maintain stable readings under load.
Precision Four Wire Sensor Design
The separate heater and measurement circuits of this O2 sensor deliver rapid warm-up and more accurate voltage readings across a broad temperature range. By isolating the heater element, the engine control unit gains real-time oxygen feedback that is essential for fine-tuning air-fuel ratios and preventing conditions that can harm engine components or damage catalytic converters. Under sudden load changes, the independent channels maintain stable data flow so tuning remains consistent and fuel economy stays optimized.
Exact Fit for Gen 4 LS 58 Tooth Ring
Engineers built this sensor to match the 58-tooth reluctor ring pattern found on Gen 4 LS engines, eliminating the need for adapters or spliced wiring. The connector's pin layout aligns precisely with the factory crank position harness, preventing signal errors that could trigger fault codes or disrupt ignition timing. This exact-fit approach ensures reliable integration with the engine's electronics for seamless operation under street or track conditions.
Effortless Connector Installation
The square four pin connector mirrors the stock crank position sensor plug, allowing builders to swap sensors without specialty tools or wiring changes. Simply unplug the original unit, connect this sensor, and secure it in the exhaust manifold bung to complete installation. This straightforward process reduces setup time, minimizes wiring mistakes, and helps maintain a tidy engine bay during any LS swap project.
Stainless Steel Housing and Ceramic Element Resilience
Crafted from corrosion-resistant stainless steel, the sensor housing protects the internal ceramic element and insulation jacket from thermal shock and vibration. This rugged construction stands up to repeated thermal cycles and engine-bay stresses, preserving calibration integrity over thousands of miles. With consistent oxygen feedback maintained even under extreme exhaust temperatures, tuners can rely on stable readings for long term performance and emissions control.
Engineered for precise readings and dependable performance in every LS engine setup.
