Precise 4-Wire 58x O2 Sensing for LS Motors

Achieve consistent air-fuel ratios across the entire LS powerband thanks to the 4-wire architecture and 58-tooth Gen 4 compatibility of this O2 Sensor, enabling accurate oxygen feedback for aggressive tuning. The square 4-pin connector delivers instant fitment while the heat-resistant stainless steel housing and robust construction withstand thermal stress for enduring performance on track and street, boosting power, improving fuel economy, and reducing emissions.

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

If you are completing 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 aligning with the factory 58 tooth reluctor ring. Its square four pin connector plugs into the stock harness so no adapter wiring is required. Engineers selected stainless steel housing and a ceramic sensing element to maintain accuracy under extreme exhaust heat and vibration. By separating heater and measurement circuits this sensor delivers consistent data from cold idle through high load operation. This direct fit solution not only saves installation time it also safeguards ECU readings for accurate closed loop control.

Four Wire Sensor Architecture for Rapid Warm Up and Stable Data

The 4 wire design separates the heater element from the sensing circuit allowing the sensor to reach operating temperature quickly without compromising measurement accuracy. Early heat investment ensures that the sensor provides stable oxygen readings immediately after engine start which prevents lean or rich spikes during the critical warm up period. By isolating the heater supply, the sensor delivers consistent voltage signals across a wide temperature range and under sudden load changes. This leads to more reliable closed loop tuning and helps maintain efficient combustion from idle through heavy throttle.

Precision Alignment with Gen 4 LS 58 Tooth Crank Pattern

This oxygen sensor is engineered to match the 58 tooth reluctor pattern used by Gen 4 LS engine controllers, ensuring the ECU receives correct timing and fuel mixture data without adapter harnesses. The square four pin connector plugs directly into the stock wiring loom to eliminate splices that might introduce signal noise or error codes. A direct fit approach reduces installation time and minimizes wiring complexity so builders can focus on mechanical integration rather than electrical troubleshooting. The precise match also safeguards ignition timing which is critical for peak performance and emissions control.

Stainless Steel and Ceramic Construction for Extreme Conditions

A robust stainless steel housing protects the internal element from corrosive exhaust gases and repeated heat cycles, while an advanced ceramic sensing core maintains calibration under intense vibration. This combination resists deformation and preserves the integrity of the sensing surface even when exposed to rapid temperature swings common in engine bays. It also extends service life by preventing premature wear that leads to signal drift. Engineers chose these materials to ensure stable oxygen feedback during spirited driving and track use.

Optimized Combustion Control for Power Economy and Emissions

Accurate oxygen data is crucial for fine tuning air fuel ratios, and this sensor provides the precise feedback required to adjust injector timing and fuel delivery in real time. Correct closed loop operation reduces excess fuel consumption and limits unburnt hydrocarbons while boosting output by maintaining the ideal mixture under all load conditions. As a result, engine response becomes more predictable and fuel efficiency improves without sacrificing throttle feel. The sensor thus plays a pivotal role in balancing performance gains with environmental compliance.

This O2 sensor ensures accurate oxygen feedback and reliable engine control in your LS swap.
