Thanks for the advice guys! I will double check the rear brakes and double check if I have any isssues.

So I went down to my local parts store and tried to get a few basic maintenance parts for my 2000 Subaru Legacy Brighton Wagon (2.5 SOHC). Wanted to buy spark plugs, oil filter and brake pads and shoes. Problem one: I refered to the Haynes manual for the correct spark plug and the manual lists it as NGK BKR6E-11. They looked up my car on the computer and said the part listed for my specific car is NGK BKR5E-11. Are these plugs interchangeable? What is the difference? Problem two: Purchased oil and a filter to do an oil change. Looked up the filter in the book and grabbed some oil and everything went great. Sort of. When I went to take the old filter off it would not fit on my filter wrench, the new one did though. Confused, I checked the two filters and found that the new filter was wider than the filter already on my car. The new filter I purchased was a Bosch 3310, is this filter just wider on the outside than some other filters or is this the wrong filter for my car? Any suggestions? Anyone care to share what filter they use? Problem three: I went to price brake pads and shoes at the counter. No problems looking up the front pads, but the computer system the associate was using did not have any listing for brake shoes for the rear brakes. I have checked my car and it most surely has rear drums but the computer insists this cannot be. Anyone have a similar car and have a part number for brake shoes? I repeated this at another shop and got all the same results, same plugs, same filters, and no shoes. The associate there did however run a check for 99 Legacys and found that some of them did have drum brakes in the rear. Could my car be a 99 sold as a 2000?

Thank you Fairtax4me, just curious but what is the difference between the different sensors, how do I tell them apart?

Hi everyone, I just accquired a 2000 Subaru Legacy Brighton and I am having a few issues with it. The check engine light is on and when I pulled the codes I came up with P0325 Knock Sensor no. 1 Circuit malfunction P0420 Catalyst Efficiency Below Threshold and P0133 02 Sensor Slow Response. I am assuming that the two sensor related problems would trigger a P0420 so I should resolve these first. What I wanted to know is if there is a difference between the various replacement sensors. In otherwords, should I buy straight from the dealer or will a Bosch sensor from autozone or napa be good enough? Also, is the slow response from the o2 sensor caused by a faulty sensor, or could it be caused by something else like a loose wire or bad connection or improper fuel trim etc? Thanks, I look forward to your help and answers and I assure you, I will probably have many more questions.
