Looking for something to help keep my o2 sensors dry. For some reason they keep getting wet and not working.

Several peeps, including Articfriends, use and promote these innovate one’s:
Lifespan on Bosch 4.9 02 Sensor

Innovate motorsports bung extender works for me too.

Not only does the innovate piece extend the o2, its also directional and shields the 02 from the water your most likely getting from reversion thats wrecking them, Smitty

Indeed....another user of said product.

Biggest issue I had was clocking it for flow direction as I had a hard time finding thin enough washers etc.

I used the same extenders , I made a fixture to hold the washer and I sanded them to achieve the correct clocked position .

I used some O2 extenders that were mentioned on here a ways back. If you do a google search for "O2 extender CEL" you'll find them. Mine had screens in them (i'm sure those help with water intrusion). My understanding is that there wasn't difference running with or without so they should give an accurate reading.

That was me. And I ran them on Smitty's (articfriends) dyno.

Just for an added data point I did direct A/B comparison both with and without the Innovate extender on the same motor, same tune, same day. No difference in AFRs.

Sorry been a bit but is this what I should order to replace what I have? Need to get these on the boat. Thanks
