Knock Sensor 10mm

Recommended Posts

Hey,

Anybody know of a Bosch Style "donut" Knock Sensor with a 10mm hole in it rather than 8mm?

Currently I'm having some step down studs made, but would love to do it with a simple sensor change instead!

Hi Grant,

If you have a 12mm hole, Toyota make these studs available for a few dollars, they're very commonly used on Toyota OEM applications to mount 8mm Bosch style sensors to an M12x1.25 threaded holes. The part numbers are:-

90126-08039 or 90126-08046 

Cheers,
Matt

Thanks,

I drilled a sensor today and tried it before and after. No difference at all when using a 10-8mm stud and 8mm hole, or using an M10 bolt and drilled sensor.

Same knock levels, same background noise etc etc.
