Designed to accept popular 18mm o2 oxygen sensors.
Marine o2 sensor adapter.
Included with this item.
Ac delco part number 213 3533.
A unique feature of this adapter is the cooling parts that run along each side of the sensor maintaining consistent temperature of the spacer.
Probably so moisture can drip off.
O2 exhaust sensor used on all marine power catalyst engines.
The adapter plate bolts to the exhaust manifold riser.
Part hm206 brass adaptor designed to install heated oxygen sensor in water cooled marine exhaust risers.
Mercury 3 and 4 riser gasket 700 32080 2 required stainless steel 18mm oxygen sensor plug 620 50031 1 required.
Gm part number 12589321.
This unique 1 thick adapter plate provides an installation option for retro fitting a oxygen sensor and or air fuel ratio gauge for tuning purposes into the most common log manifold style exhaust systems.
Oxygen sensor is sold separately adaptor should be installed in a flat area of riser at least 6 before water blends with exhaust.
Designed to accept popular 18mm o2 oxygen sensors.
This unique 1 thick adapter plate provides an installation option for retro fitting a oxygen sensor and or air fuel ratio gauge for tuning purposes into the most common log manifold style exhaust systems.
And with the o2 sandwich plate between manifold and riser the sensor is mounted.
The outer portion of the adapter seals with a threaded flange and o ring to prevent cooling water leakage.
When installing an o2 sensor in our water cooled manifolds both of these criteria seems to be hard to match.
Designed to accept all popular 18mm o2 oxygen sensors.
The part is manufactured from aluminum and is not treated with any corrosion resistance.
Description pictured is a custom made adapter plate for marine applications that choose to add a heated three wire or four wire o2 sensor for use when converting an engine from an open loop system to a closed loop system.
It will not fit on round or oval risers without a suitable flat area.
When going 18 inch away from the nearest exhaust port we are almost out where the water is mixed with exhaust.
