O2 Spacer, For Common Log Style Exhaust manifolds

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. The part is manufactured from Aluminum and is not treated with any corrosion resistance. Designed to accept popular 18MM O2 Oxygen sensors.

TECH NOTE: Will O2 Sensors Work In marine exhaust systems?

YES FOR TUNING but they have limitations as water / moisture is a byproduct of combustion. Often boaters find there is moisture in their exhaust system that have collected or made their way inside of what is better known as the "DRY" exhaust stream of their exhaust system. Anything from steam like to little water droplets about 1/32" all around the inside of the exhaust. This is because water IS a by product of combustion. same thing you see on a cold morning behind cars. sometimes you see water dripping out.

Don't take our word for it ask a real rocket scientist: https://www.grc.nasa.gov/www/k-12/airplane/combst1.html

This is why O2 Sensors are great for tuning but have a limited long term life span unless protected by Catalytic converters like on New Marine engine offerings. So you know gas is known as a hydrocarbon based fuel. And we all know what hydro means WATER.
