Product Description

Want to closely monitor Air/Fuel ratios on your carbureted or EFI vehicle? Holley has just the product for you. Holley is proud to introduce the Holley Wide Band O2 Controller with gauge.

A wide band oxygen sensor is the ultimate addition to any carbureted or EFI vehicle. It will accurately measure any air/fuel ratio between 10:1 and 18:1. This allows the engine tuner to read the air/fuel ratio in real time for extremely accurate tuning.

The 534-201 kit is intended for the consumer who wants to be able to accurately measure air/fuel ratios so the perfect tune up can be obtained. The 534-201 can also be upgraded later for use with an NTK sensor by simply reconnecting a jumper loop and purchasing the NTK sensor (P/N 534-194).

The Holley Wide Band O2 gauge features a 3-digit numeric display along with a 40 segment bar graph. With the ultra-high intensity light emitting diodes you will be able to see your Air/Fuel ratio even under direct sunlight.

The P/N 534-201 is designed to operate in street or race environments and will withstand heat, dirt, and vibration. The Holley Wide Band O2 gauge will fit in a standard 2-1/16” gauge pod.
