Is this the solenoid on the starter itself? That's probably not out of line for OEM parts. If that's the one, I'd take it to a shop that repairs starter/alternators/etc.
If it's a standalone solenoid, those are usually pretty generic...

ditto that.
for parts with a part number.. google them.
for filters.. I've found you don't save much by ordering them or driving around to get crosses. my local dealer has fairly competitive prices on most filters.. and at least I know they are correct and not just close 'xref'
