RICE RACING will become famous soon enough
P.S. I don't sell the other sensors either BTW!

They will most likely fail as well in time due to being weak open element types too! There is a reason Mazda did not use these in the rotary engine and I can see why now after accumulating allot of testing hours and time and kilometers on them.

The same fatigue happens to open element EGT wires as well for your information, and no I dont sell others ether of those. Just passing on real knowledge and testing which fuck all other people do or have the ability or running cars to do so.

In the rotary engine especially the 13B-REW with its dynamic chamber intake manifold and where the AIT sensor is placed it sees large "pulses" and these over time flex the sensor wire back and forth, you need to do many km's like I stated in my first post, and I guarantee you this will fatigue the wire or wires and it will go open circuit.

I have see this happen in egt sensors and also in these AIT sensors (if you sell them or not is not my issue nor my aim to warn people@) its just that this type of sensor WILL fail in a rotary engine over time.

Typically its happened on 2 different cars at around 10,000km covered range. both 13B-REW's with stock intake manifolds and positioned sensors. Take that for what you will. The sensor tips did not fall off into the motors but one wire on each sensor was broken due to the constant flexing the exposed sensor tip is subjected to. And as I stated its a well known fact that open element EGT sensor tips suffer the same failures due to pulsations breaking wires as well.

When the sensor goes south least the motor will run rich if you have the ECU set up correctly for it.
