I can order any length lead needed and it is a simple plug-in for the extension if adding length. That's for the Daytona Sensor Wide Band

Ok correction :the only system I found that had 20' lenght

Where are you guys locating the sensors? Anyone using a spacer or similar?

I put them on my cmi tails close to the dry joint from header to tail and about 12 inches from water dump. I never had an issue while running, however I left the 02 in there over night with the boat in the water and it ruined the sensor.

I woul love to have them live all the time, but I am not cutting into my headers. The replacemt sensors are 60 percent of the cost of the innovate mtx-l

I only get about five or six hours on port engine before the o2 sensor dies. Starboard side is still running original after 50 hours.

Weird, I know.

Has anyone ever used the extensions that move the sensor out of the exhaust flow?

I think the Merc 496 style exhaust used the turbulators to prevent condensation that built up inside the riser from leaking down into the exhaust ports........ I may have an issue with that living in the humidity of Florida...... TBF
