Has anyone ever tried the Standard Motor Products knock sensors? AutoZone wants about $100 for the sensor and Amazon wants $23 for an aftermarket one. I'm not wanting to spend $100 on a sensor so I just want to make sure the cheaper one will do the job for a few years.

The part number for the aftermarket sensor is KS305.

 

That's the knock sensor I bought. It worked fine, 1100 miles and no problems so far. A hell of a lot better than 100 bones!
