Reliability Mods

[Gobemouche]

Hello!

I've got my first impreza hatchback (2019 manual trans) and want to install some baseline mods to make this thing more reliable. I bought it at 40k miles and it runs well so far, but I like driving slow cars fast and want to get some ideas on how to make sure I don't starve the engine of oil or something like that. I've never worked with AWD, boxer engines, or even double wishbone suspension before so this is all new to me.

I know the WRX and STI models have performance oil pickups/baffles and a variety of air/oil separators avaliable but I have no idea what the cross compatability is for the base models (if there is any at all).

Any suggestions on mods, brands, and general tips would be much appreciated!
