Review on uxcell Knock Sensor 22060-AA070: Enhanced Replacement for 1999-2000 Subaru Legacy Impreza Forester & 1999-2001 Subaru Outback by Kenny Marozas

So far so good, it has been installed and has been working fine for about two months. One from the auto parts store is about $100, so it was worth it. There isn't much of a difference with aftermarket parts, they either work or they don't, just make sure the end of the connector matches yours and the screw needs to be torqued correctly. I think 15 kilos, but I can't think of it now. ;-) Ok update a year later I get the po325 knock sensor code again. I think this time I'll bite the bullet and get a better one from the parts store. You can get it for around $30 with an online code for a 25% discount. In my mind, my time is worth not doing it again.
