Lambda sensor adapter with M18 – M12
Adapter for mounting a 18mm wideband lambda sensor in place of the factory 12mm narrowband socket.
Ideal for AFR measurement, ECU tuning and engine diagnostics without the need to weld a new socket in the exhaust system.
The adapter is screwed directly into the serial hole of the M12 narrowband probe and then allows the M18 broadband probe to be mounted.
Product Features:
-
allows the broadband probe to be mounted in place of the 12 mm narrowband probe
-
no need to intervene in the exhaust system (no welding)
-
ideal for AFR measurements, tuning and diagnostics
-
solid workmanship ensuring tightness of the connection
Dimensions:
-
Ø2 adapter height: approx. 32 mm (counting vertically when installed in the series location)
-
Required space for the broadband probe: minimum 70 mm of additional height over the adapter
Important information:
The product is universal. Depending on the design of the exhaust system and the placement of components in a given motorcycle or vehicle model, there may be problems with the mounting location.
Before purchasing, make sure that there is enough space at the mounting site for both the adapter and the broadband probe itself.
In case of limited space, it is recommended to:
-
use of a dedicated M18 socket for welding into the exhaust
-
or using an angle adapter (e.g., 12 mm → 18 mm) that deflects the probe and helps solve the problem of collision with other components
