I decided to take care of a small maintenance item. A previous owner had the OEM air filter on the Cadillac replaced with an Airaid cold air intake. I purchased the car in 2016 when it had 11,700 miles on the odometer. I have no idea when it was installed but now that it has 18,617 miles on it I wanted to clean it. I don't expect it's filthy but I replaced the original cabin air filter and it wasn't filthy but definitely needed to be replaced.
I put a CAI on the PT Cruiser when I replaced all the accordian intake ductwork with smooth aluminum tubing so I expected it to be a simple process of loosening a clamp. The filter is hidden under the metal cover, fastened with four button head allen screws.

Once I had the cover off, the filter is right there. Unfortunately there's no way to pull it out through the top. The plastic covers pop right off but no matter how many I removed, it is obvious the housing has to come out as well.

Turns out the housing has two fasteners holding it place so it wasn't that big a deal. However, the area nearby looks like a plastic graveyard. Also, whoever installed this thing failed to tighten one of the worm screw clamps but also failed to follow Mike's (@zmotorsports) instructions on using Syl-Glyde on the rubber (it was like they were glued on). As long as I was in there, the plastic got a thin coat of 303 Aerospace Protectant.

I am totally spoiled living where I do. I spent a huge amount of time washing the dust and dirt that has accumulated. on the pieces I removed.

I took the mass airflow sensor off the Airaid Intake Tube so I could wash it inside and out. Sadly there wasn't much of anything inside the tube but it got its own coat of 303.

I went looking for the filter element cleaning and oiling kit I had for the PT Cruiser setup but took a deep breath and Googled the Airaid instructions and printed out a full color copy. Turns out this filter isn't supposed to be oiled. The end of the filter has a reminder on it.

All you have to do is spray household cleaner like Simple Green or Formula 409, neither of which are in my collection. Used Purple Power instead and let it dry out in the sun. I was hoping to find some gum or carbon buildup in the throttle body so I could spray some Berkebile Gum Cutter on it. Decided it wasn't really needed.

Put it all back together and of course I dropped the washer that goes on the second mounting bolt and it made the sound of falling all the way down and out of sight, probably laying on the plastic shield behind the front splitter. I'll retrieve it when I change the oil (changed it 1,148 miles and 22.5 months ago).
