Direct-Fit 4-Wire O2 Sensor for LS Engine Swaps
For builders installing an LS powerplant, getting reliable oxygen readings is non negotiable and the 4-wire O2 Sensor - 58x Gen 4 simplifies that task. Its square four pin connector and dedicated 58 tooth reluctor ring interface ensure plug and play fit with Gen 4 LS engines. Durable materials and precision calibration keep readings consistent under high stress and elevated exhaust temperatures.
Precision Oxygen Monitoring with Four Wire Sensor Architecture
This four wire O2 sensor separates the heater circuit from the measurement circuit, delivering fast warm-up times and more accurate voltage readings. By isolating the heater element, the engine control unit receives real-time feedback on exhaust oxygen levels across a wide temperature range. This precision monitoring is essential for fine-tuning air-fuel ratios and avoiding conditions that can damage engine components or catalytic converters. In high load or transient conditions, the independent channels maintain stable data flow, supporting consistent power delivery and fuel economy.
Seamless Integration with Gen 4 LS Engine and 58 Tooth Ring Interface
Designed specifically for Gen 4 LS platforms, this sensor plugs directly into the factory crank position harness that uses a 58 tooth reluctor ring pattern. The connector pin layout and reluctor interface match the original equipment configuration, eliminating the need for custom adapters or splicing. This exact-fit approach prevents signal errors that could trigger engine fault codes or disrupt ignition timing. Builders benefit from a component that aligns perfectly with the engine's electronics for reliable operation under demanding driving conditions.
Simplified Plug and Play Installation Using Square Four Pin Connector
The square four pin connector mirrors the factory crankshaft position sensor plug, allowing immediate installation without specialty tools or wiring changes. Technicians simply unplug the stock sensor, connect this unit, and secure it in the exhaust manifold bung. This straightforward process reduces fitment time and minimizes wiring mistakes that can lead to erratic readings or diagnostic trouble codes. Whether on a restoration or a fresh swap project, the sensor's ergonomics speed assembly and help maintain a clean engine bay.
Robust Construction for Heat and Vibration Endurance
Built to endure the extreme environment of an exhaust manifold, the sensor employs a stainless steel housing and a durable ceramic sensing element protected by a high-temperature insulation jacket. It resists corrosion, thermal cycling, and engine-bay vibration that can degrade lesser units. This rugged design maintains calibration integrity over thousands of miles, ensuring consistent oxygen data for optimal tuning. By withstanding under-hood stresses, the sensor helps safeguard engine performance and emissions control throughout its service life.
