If your anything like me, you hate trying to find Subaru part numbers when ordering. The purpose of this thread is to list commonly replaced and used Genuine Subaru parts and their respected numbers for easy reference. This thread will be a continual work in progress so be patient and understanding. Always double check your number and application before purchasing. Subaru is continually changing part numbers and one part may fit many different applications. I only want to list numbers and fitment you are absolutely, 110% sure is correct. So if you bought a gasket for your 07 wrx but think it will fit all 02-07 WRX and STI don't say it will unless you have confirmed it in a legitimate way (online part number search, personal experience, exct...). If you have a contribution you can post it in the comments and i will add it to the origional post or you can message me or maybe a mod if they are willing to help upkeep on this. Look to make sure it is not on the list before contributing in a effort to avoid double post. If you see an error or know a part is confirmed to fit something else then please share. Do not use this thread as a parts bible. Use it as a general reference and starting point on hard to find numbers.

This is that bolt.If you are up-grading the small idler pulley on your 2002 - 2003 WRX to the newer 2004+ small idler, pulley, this is the bolt that you will need to make that work.This is also the bolt you will need if you are using the 2004+ Gates Racing Kit if it is for a 2002 - 2003 WRX.

These are the bushings in the "dogbone" in the rear diff / subframe.This bushing pair came on the STi models, but will fit in the other Impreza models. It will lessen the slop in the subframe and make the car more responsive during aggressive driving. The bushings would be a worthwhile upgrade or a worthy replacement!

Long bolt for small idler pulley: This the bolt that attaches the small idler pulley for the timing belt on the Subaru EJ series engines. From 2004+ the small idler pulley was re-designed to incorporate 2 bearings instead of 1. This vastly improved the small idler pulley's reliability, but it requires a longer bolt.
This is that bolt.If you are up-grading the small idler pulley on your 2002 - 2003 WRX to the newer 2004+ small idler, pulley, this is the bolt that you will need to make that work.This is also the bolt you will need if you are using the 2004+ Gates Racing Kit if it is for a 2002 - 2003 WRX.

Bushing: . This will fit in all models of the 2002-2007 Subaru Impreza. These are the bushings in the "dogbone" in the rear diff / subframe.This bushing pair came on the STi models, but will fit in the other Impreza models. It will lessen the slop in the subframe and make the car more responsive during aggressive driving. The bushings would be a worthwhile upgrade or a worthy replacement!
