Knock sensors detect detonation, or pre-ignition. With each "knock", or ping as it is usually described, micro bits of metal will be etched away, from most likely the spark plug tip and/or the piston.
In extreme cases, I have seen spark knock eat a hole in a piston. It looked as if someone used a sandblaster to blow a hole in it. This was a carburated, old american junker. NOT an s2k.

We'll see how everything pans out.

Many of us think that the difference in knock sensor price is not worth the risk. True. However, the argument itself is meaningful.
I agree that the car might operate with no CEL. But, I think the ECU works as follows: it retards the timing until no knock is read from the sensor. Therefore, if the sensor is more sensitive than the actual OEM proposed one, the car might retard timing more than it should and hence, you'll be running fine, no reliability sacrifice, but more fuel consumption and less power, that you most likely not notice. AND CEL will not tell you
Though, the question is this: "if a CIVIC or ACCORD 4 Cyl block that is close to an S2000 block are using different sensors, why is a 2.0L S2000 using the same knock sensor as the 2.2L sensor"? I read it earlier in this thread, a fellow suggested. A mechanic as I remember.
How much different a knock sound is from a CIVIC to an S2000!!?!?!

Fuel consumption has been the same. Also I would like to add that the motor it came from is a '03 civic si with a 2.0 litre.. it is a stock OEM sensor, and is brand new. The car has been running great, and ( don't get mad at me, but for daily use I use 87 octane. ) so I have tested it with low octane no difference, and I don't even notice the high octane difference on a stock S2000. I will be getting a AEM stand alone soon and we'll see when i test a S2000 knock sensor compared to a civic si knock sensor. Thank you.

What are the changes that make a knock sound changes?
Piston shape?!?!
I'm still wondering why the same knock sensor is used for F20 and F22 while it should be difference than a civic or accord 4 cyl 2.0 or 2.4 similar block?
