❓ Frequently Asked Questions
Q Does the air-fuel ratio gauge come with a sensor?
No, the air-fuel ratio gauge does not include a sensor. You will need to purchase a narrow band oxygen sensor separately. It is not compatible with wideband oxygen sensors.
Q What is the sensor thread size for these gauges?
The sensor thread size is 1/8ZG, which is a standard size compatible with most automotive applications.
Q After receiving the gauge, the pointer is not at 0 — is there a problem?
This is completely normal. The pointer may not rest at 0 before power is applied. Once you power on the gauge, it will operate correctly and display accurate readings.
Q What is the difference between the Boost Gauge PSI and Boost Gauge Bar versions?
The Boost Gauge PSI version (-30 ~ 35 PSI) includes turbo function support. The Boost Gauge Bar version (-1 ~ 2 Bar) does not include turbo function. Choose based on your preferred unit and vehicle setup.
Q What vehicles are these gauges compatible with?
All gauges are suitable for 12V gasoline vehicles. The tachometer specifically supports 1 to 8 cylinder engines. These gauges are not designed for diesel vehicles or vehicles with different voltage systems.
Q Do the gauges come with installation instructions?
Yes, English installation instructions are included in the package to help you with the installation process.
