Syvecs 2.5 PnP cable + NTK Lambda Sensor

Syvecs NTK LZA08-H5 Wideband Sensor and 2.5m PnP Cable

The Syvecs NTK Wideband Lambda Kit is the professional's choice for air-fuel ratio monitoring in extreme performance applications. While the Bosch LSU 4.9 is excellent for most street and track cars, the NTK LZA08-H5 sensor is highly regarded in the motorsport industry for its superior resilience to leaded fuels, high exhaust gas temperatures, and the aggressive combustion pressures found in high-boost drag racing and endurance engines.

This kit bundles the genuine NTK sensor with a 2.5-meter Plug and Play (PnP) extension cable, providing a complete solution for Syvecs S12 and X-series expander users who require the most robust Lambda sensing available.

Performance and Precision Engineering

The NTK sensor is preferred by elite tuners for its stability and "rich-end" accuracy, which is critical when tuning 2000hp+ methanol or race-gas engines.

• Motorsport Durability: Highly resistant to "poisoning" from leaded fuels and oil additives, ensuring a longer service life in extreme environments.

• Thermal Management: Designed to operate accurately at higher temperatures than standard wideband sensors, reducing the risk of sensor "dropout" during a high-speed pull.

• Signal Integrity: The included 2.5m cable uses high-spec shielded wiring to protect the weak current signals from the electrical noise generated by high-output ignition coils.

• Closed-Loop Mastery: Allows the Syvecs ECU to perform millisecond-speed fuel corrections, maintaining engine safety even if fuel pressure or ambient conditions fluctuate.

Wiring and Connection Data

The NTK sensor utilizes a different control strategy than the Bosch units. Ensure your Syvecs ECU or expansion module is configured for NTK logic in the SCal software before use.
