Thanks for the comments all. The reason I am changing it is to resolve a P0325 or Knock Sensor 1 Circuit Malfunction. I understand that may not mean the sensor and could be the wiring but I am hoping for the best. Yes the CEL is lit and as I mentioned the car is driving "ok" but not great. I am thinking that there is some mild knocking going on, although not audible, and because the sensor (or cuircuit) has malfunctioned the timing is not being adjusted correctly resulting in sub par performance. I have alleviated the problem by moving to the highest grade gas available - I can't imagine this causing a problem, can anyone comment? I am glad this forum exists there are few forums that exists with this number of knowledgeable and helpful individuals.

Thanks Cougar!

98 Subaru 2.5L outback. Trying to locate a source for a knock sensor - been to the obvious places i.e. Parts Source, Crappy Tire etc but they either want to much $$ or it will take 2+ weeks to get it. The car is driving ok currently - can I afford to wait? If not where should I look for one? Thanks in advance!
