    1.) unplug the battery
    2.) remove airbox and possibly washer fluid reservoir
    3.) remove coil packs
    4.) remove spark plugs
    5.) install new spark plugs (gapped properly) using LocTite and the torque specs specified in your shop manual
    6.) drink beer.

    I would modify it slightly:
    1.) Remove air box
    2.) Remove battery
    3.) Remove air pump off front of engine (and pipe attached to it)

    Then carry on with your #3-6.

    Ok guys. I think I got lost between the drink beer and the drink beer. So I think I'm just going to call it a day and drink a beer or two.
    Try it tomorrow. Lmao

    Meh, most recently I was able to pull the plugs and do a compression test with the battery still in the car, though it might be due to the fact my Optima Yellow Top is smaller than the stock battery.

    What's that?
    Even my friends 05 STi engine bay is different from mine when the 2.0L go to do a compression test. In my engine bay it would be near impossible to get the coils out with the battery in there. My friends 05, it'd still be difficult.

    You'll find the air pump... a giant plastic tube covers up most of both driver side coil packs =P

    I haven't worked with a 2.0L ever, so I don't have much comparison to offer directly to yours obviously.

    EDIT: Looking at pictures, it seems the battery has kinda been wedged around a bit differently over the years. Also, the obvious difference of no wiper jug over that way on the newer ones. Hopefully your 2.0L ones are easier though.

    I think next time I am going to jack my engine up an inch or so. I have a bad feeling that the compression checker adapter is going to get stuck in there or something, and I won't be able to drill it out. I may just glue the adapter on as well I guess.
