Site with part numbers
 

Is there a Scion/Toyota or Subaru website that provides part numbers with the diagrams? All Subaru sites I've seen only provide a description and price of the part but no part numbers. Would be helpful when calling your local dealer for parts by providing them the part number instead of trying to describe to them the part.

the best website for parts is techinfo.toyota.com but unfortunately, it's not free.

They don't give diagrams though so you'll pretty much have to know the names of the parts. Most sites have the same prices for parts so as long as you have a diagram to cross-reference, you should be good despite having different part numbers associated.

I guess I'm spoiled by Honda/Acura parts sites. :(

#1 hit when googling "subaru parts"........

I swore I could find the part # last time I was on the site, now ???

I hate not knowing the part number before buying a part. How am I supposed to verify that I'm buying the right part? Call them before I make each purchase?

It doesn't seem to have all pars, but its a start.

You can also get the copy of the car diagrams and that includes part numbers.
