Shoot, I've got a stock pair of P5 headlights that just need a polish. I should have put them up for sale on here earlier heh.-Installed the Downstream an O2 sensor "Defouler" adapter to get rid of the
P0421 CEL (Pre-cat) code that recently popped up a couple times after clearing other codes (photo attached).
--I used PB Blaster to wet the 02 sensor base down overnight and right before removing the sensor and used a 3 piece 02 sensor "free rental kit" (pay for it and get reimbursed when you bring it back) from Advanced Parts Store that worked REALLY well removing it.
-Installed a piece of 2" I.D. Sch40 PVC Pipe X 3" long into air inlet pipe where upper cover enters lower pipe (no gluing-just drop it in).
--That area doesn't have a good seal (at least not on this P5) so it bridges the air gap so air can flow straight through to the air cleaner and beyond.
--The pipe sits above the 90* turn opening to the air cleaner so does not interfere with the air flow.
-After finishing installation of front bumper and new aftermarket headlights (that have 2 beam adjusters vs 1), I tried to adjust high and low beams and found out that one of the adjusters on each fixture is buried behind some of the radiator support/fender metal work that can't be accessed from the back (photo below).
--The company brand (DEPO) made a slotted adjusted wheel provision to turn them with a tiny screwdriver along with a "capped" headed Phillips/Bolt head, and is a PITA to rotate in those tucked away areas.
--If someone chooses to buy these fixtures, I would recommend cutting a little bit of metal away in the corner where they will mount to where you can have access to get at the adjuster from the rear through the fender-well area.

--The do have bigger screws and wire clip holder arm shown in the photo below so that's an improvement over the (IMO) crappy original equipment lightbulb installation design.
I personally like the plug it in and rotate-it-to-lock design.
Not sure if you tried this, but I believe that adjuster is meant to be rotated using a Philips screw driver. I figured that out when I installed my retrofitted headlights a month back or so.
Brought forward from your original list of things to do.issues I need to address are...a couple of CEL codes.
FWIW, these are like $18 from Amazon and install in a few minutes. If this doesn't clear the CEL, then you might also need to get a Charcoal Purge Valve (it's under the rear bumper).
