Narrowband Mixture Indicator

The SPILBA NARROWBAND / HALLMETER AIR/FUEL RATIO GAUGE is designed to measure the air-fuel ratio at the exhaust outlet of a 4-stroke engine. Its sleek design, ultra-compact size, and high-brightness LEDs make it ideal for referencing the mixture range at a glance.

Knowing the air/fuel mixture ratio is essential to achieve peak performance in combustion engines. Poor carburetion can result in a rich mixture, leading to high fuel consumption and reduced performance. On the other hand, a lean mixture can cause pre-ignition (knocking), which—if repeated for just a few seconds—can raise pressure and temperature inside the combustion chamber and cause irreversible engine damage. This gauge can be used in race vehicles as well as street vehicles!

Compatible with 1, 2, 3, and even 4-wire O2 sensors.

Our Narrowband Kit includes the indicator and a Universal 4-wire Bosch sensor!

Ideal for use in cars, motorcycles, karting, and test benches.
