Knock Sensors

[Aptyp]

Where to get them for much less, than $65 a piece. Seems really expensive for what they are.

65 is not bad. I get my parts at cost from BMW due to a deal I made with one of the managers and they are not cheap at cost.

I know... But I am just about to buy m52 knock sensor and modify the plug. It's unreasonable to spend $130 on knock sensors, when m52 ones can be had for around 50 for both.

[samiam3356]

Anyone ever checked to see if they are compatible beside the plug? Would suck to be running into issues because of this though.

they are not compatible, even with a plug change. I tried, it will throw the CEL

[samiam3356]

OK that make sense then

I recall looking into that, too. It was that the type of sensor or the number of wires used was different. It wasn't just a one plug/two plug thing.

[Aptyp]

so is there a good place to get them cheaper then? or should I start going to junk-yards to see if I can find uncracked ones?

I ran a S52 knock sensor on my OBDI S52, and also now on my DD 95 M3.

Neither threw/throws a light?

Cut the connector off and spliced on the M50 BOSCH type connector.

I have a pair of used ones. pm me an offer if you want them
