Sensor Air/Fuel

The RACEPAK Sensor Air/Fuel (Model 810-SN-AFAMP) is a precision oxygen sensor designed for performance monitoring and engine tuning in high-output applications. This single-channel replacement sensor integrates seamlessly into RACEPAK data acquisition systems, providing real-time air-fuel ratio feedback essential for optimizing combustion efficiency and engine performance across varying load conditions.

Built to OEM specifications, the RACEPAK air-fuel sensor delivers accurate lambda readings critical for tuning operations. The compact form factor (3.65 × 1.4 × 6.4 inches) and lightweight construction (0.28 lbs) allow straightforward installation in exhaust manifolds or downpipes without adding significant weight or bulk. Oxygen sensors in performance systems monitor combustion byproducts to calculate precise air-fuel ratios, enabling technicians to dial in fuel maps, verify knock margins, and confirm proper ignition timing across RPM ranges.

This replacement sensor is essential for racers, dyno operators, and engine builders who rely on real-time data logging to validate tune changes and monitor engine health during development and testing. The 810-SN-AFAMP sensor replacement plugs directly into existing RACEPAK wiring harnesses, minimizing downtime between runs. Technicians working with single or multi-channel monitoring systems will find this OEM-spec sensor delivers the durability and accuracy needed for consistent baseline measurements across multiple sessions.
