I'd like to know the same thing on the Tour-X. I think it's behind the glove box, but how do you drop the glove box to get to the filter?

That being said, I no longer think about, or worry about changing the cabin filter. Years ago, I had a Continental whereas the filter was in front of the windshield, under the air intake. Car had 85,000+ Miles and never had cabin filter changed. (A/C and heat worked fine). Decided I'd check it out so I found and removed it. Yes, it was dirty and loaded with leaves. Shook it clean, then vacuumed it. Replaced it back. Never worried about replacing (or paying for replacing it).

Dropping glove box is pretty simple - there are plastic clips located on the inside "ceiling" of the glovebox (which act as retainers). Push the glovebox in a bit, and push the clips above the rear wall of the glovebox. There is also a damper on the left side - of which the arm slides off the pin (pin is affixed to glove box). The glove box bin will drop straight down.

Replacing the cabin air filter after a year is a bit too soon if you ask me. According to the owners manual it should be replaced every 22,500 miles.

What about engine air filter? Is K&N 33-5049 the only option we have for high flow aftermarket filter? It needs to be oiled and it costs $60. I had Upgr8 aftermarket dry filter in my previous Scion and it was just $10, but it worked as good as K&N.

I went through a K&N phase in 2004. I also don't notice any advantage to using them. I've since been using Wix or other cheap alternative. As long as it fits and is durable enough, it works for me.

To each their own. We have really bad pollen around here, so I do mine annually in my cars. Haven't tackled the TourX yet, but when I do it I can create a how-to post.

I would agree, but I did notice a significant difference when I installed high flow aftermarket engine filter in my previous car. Sure it was a weak 1.8 liter Scion, so I wonder if it makes any difference on our cars. If K&N is good for ~50,000 miles, it is worth the investment. OTOH, those filters probably cost around $3 to manufacture, so they are making a huge profit.

...but disconnect the battery before going any further--there's an airbag mounted under the glovebox.
Reviving this thread because I'm due to change out my cabin filter but a little concerned by this statement. How would moving the glove box and cabin filter affect that airbag?

Just a reminder to error on the side of caution.

There are four airbags (explosive devices) mounted in the dashboard (5 if you include the steering wheel), and there is a human tendency to think that 'airbag' means steering wheel and since you're not doing anything with that, there isn't any problem, even though if you are asked, you will say there are multiple airbags in the car. When I was removing the HMI module (behind the glove box) I was wondering what that long metal box was just underneath the opening was; likewise when installing the sport pedals. And since your face is just a few inches away...well, it takes less than 30 seconds to disconnect the battery.

Thanks for the only simplified answer from a guy who knows his stuff. The box can be dropped down in about 60 seconds without tools. The cabin air filter is directly behind and requires releasing 2 tabs on the sides, again without tools! Believe it or not a Buick dealer told me it takes about 45 mins. I looked at him and said seriously, to the service manager. Do you still scare consumers with that tactic? I, of course, will never reveal my knowledge base to any dealer in an effort to see if they are being honest with me.

2. Flip down the door
3. Remove and replace the filter

Your first picture is incorrect for a 2018 Buick Regal. There are no screws to be removed. See thread No 4 for proper removal. Picture of filter replacement is however right on.

I just replaced both air filter on my 2018 TourX (same procedure as the sportsback). Here are the 2 links to videos showing you exactly how to do it. (You can also google "2018 Buick regal cabin (or engine) air filter replacement" to find instructions.

For the cabin air filter - After watching the video, I literally took only 2 minutes to replace mine. No tools needed. My cabin air filter at 30K miles look relatively clean, but had some plant based debris and some dead bugs on it.

For the engine air filter, it is a straight forward 6 screws removal, pull out the old one and vacuum out the dirt/sand (optional...doesn't hurt if you leave it in the there), put in the new filter, check to make sure the edge seal is flush with the air box, then put the cover back in and tighten the 6 screws. The slightly tricky part is aligning all 6 screws back in the hole, since they are self-retaining, and getting all 6 to seat properly before tightening down may be frustrating to some people and add an extra minute of work...

I brought both filters cheap from Amazon. No need to go to the dealer for this work.

Also, do yourself a favor and stay away from the charcoal coated filters. While they may be ideal for chronic asthma suffers who need the freshest possible air, they require changing almost annually and at least 2x a year. The reason being is that they will begin to stink once saturated from smog in bumper to bumper traffic. Use your recirc button if you expect to sit in traffic longer than 5 mins. It will lower your annual replacement cost on cabin air filters.

Believe it or not, they probably use book time to quote you the procedure. It's nice you were so polite to them, then bragged about it online.

If you already have all the knowledge, then why bother asking them (or anyone else for that matter)?

ACDelco currently has a rebate for all filters this car uses. CF185 is currently $15 on Amazon and has a $5 MIR. PF64 Oil filters are locked in a bot battle with Wally World and are only $2.58 and have a $1.50 MIR. Submitting rebates online is fast and mine was approved in one day.

...but disconnect the battery before going any further--there's an airbag mounted under the glovebox.
Haha, don’t do this. If the ignition is off the system is dead...as GM learned from the ignition cylinder recall...just drop the glovebox after emptying it and change the filter. It takes less than 5 minutes your first time, 2 the next.
