He mentioned two. Are you referring to the Innovate Heat Sink Extender ?

You might have to play with various washers to clock the intake port into the exhaust stream. It is actually designed to protect from overheat from a turbo application, but works well for errant water that may enter the exhaust.

That's pretty neat.. looks like Amazon has a bunch of different extenders but I wonder if they would be accurate with the o2 not in the exhaust stream and only a small hole in the extender.

I tried the Innovate heat sink and felt the readings were not accurate ..but that was when I had leaky headers ..

Did you get the same reading using that 90? Im fighting a boat right now that has lightning headers and kills sensors left and right.

The way to keep those sensors alive is to use a cam that won't revert water. Or extend the exhaust way out dry. I gave somebody on here some crap about the extender recently, cuz those 90 degree extenders were invented to fool car ecm's with bad catalytic converters.
But in retrospect I can see how it could succeed in a boat. Boats often run at a steady state so they would have the same reading once the exhaust gas hits the sensor. Cars have constant change in the throttle position, so that's where my attitude came from.
I finally installed my own AEM kit literally yesterday and only ran it for a few minutes on muffs. It did not get wet even though EMI had put my sensor bung in horizontally. When I had them warranty out my riser they did the bung. I hadn't yet seen AEM's instruction to tilt it down at least 10 degrees, and don't mount it vertical. Apparently straight down burns them up and flat can hold moisture.
I'm looking forward to fine adjusting my carb. Then I'll pull off the sensor to save it.
You all that have sensor EFI don't get that choice so you need a solution that will let the sensor live.

So you got a good reading with all that?

The situation Im dealing with is I made the mistake of agreeing to my customer buying lightning headers, cam is fairly small, their headers are a TERRIBLE design and their o2 bung location is un-usable.
