The Narrowband to Wideband O2 sensor adapter screws into a 12mm Narrowband bung, allowing you to use a Wideband O2 sensor with a Narrowband bung.
Please Note: This is a generic item and may not fit all makes/models due to potential clearance issues that arise from the manufacturers' designs. Please ensure you have adequate clearance for the adapter -AND- the O2 sensor when installed in the factory narrowband location.
- O2 Adapter Height: Approximately 32 mm extending vertically when installed in the stock narrowband location.
- O2 Sensor Height: Plan for at least 70 mm of additional height on top of the O2 Adapter when the wideband O2 sensor is installed.
For models where clearance could be an issue, it is suggested to use the wideband bung included in the Zeitronix installation kit or find an alternative narrowband to wideband adapter such as the Innovate 12mm to 18mm O2 BUNG ADAPTER, P/N 38350 which angles the sensor to help potentially alleviate any clearance issues.
