Default Does anyone have a parts compatibility list for ej20x engines?

In have a 2003 legacy that is imported from Japan. Ej20x is the engine code. Lots of parts seem to be the same as the north American wrx engine. But I'm looking into replacing more things. (coil packs, fuel filter, and some sensors perhaps) in an attempt to combat an engine issue.
Most specifically looking into the coils.

Also pcv valve. I can't find any information about legacys. Feel like I'm going to be chasing part numbers all the time. Thanks to anyone who can save me some time!

I don't have anything specific to the JDM vs. US engines but generally the US parts have been 1 model year behind the JDM. Looking into it the EJ20X was a rare beast outside of Japan, so information is scarce. It is very likely that the coil packs, fuel filter and most sensors are the same as most other EJ series engines of the same vintage through, as most EJ parts are interchangeable to a pretty good extent. For coil packs and sensors I recommend going with OEM Subaru parts as I've had some trouble with aftermarket MAF, knock, and O2 sensors on my car.

Dang i just bought a coil pack for my EJ20x - i can tell you they had one up at OReilly so it wasn't hard to find. We basically visually matched it since i had the old coil to compare with.
