Cheapest plug and play knock sensor for the 3S-GTE?

What is the cheapest but "plug and play" (as in requiring no modifications, will screw in and plug in without any issues) knock sensor for the 1991 MR2 turbo?

The factory sensor is the only one I can recommend. There is a GM knock sensor that some use but it isn't plug ang play.

What about this?

Knock Detonation Sensor - Lexus Toyota - 89615-20010 - New | eBay

It has the right part number, and is extremely cheap. Does it even look like it will fit?

If you want your CEL to turn off and your ECU out of limp mode that'd probably work. Will the ECU know how much the engine is knocking? Who knows

You only have the option for an OEM gen4 sensor, everything else is aftermarket.

This is a component that protects your engine from destruction. I would not want to experiment with it.
