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.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.
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.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.
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.I went through a K&N phase in 2004. I also don't notice any advantage to using them.

K&N also has a reusable cabin air filter which does not need to be oiled. Here:
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?...but disconnect the battery before going any further--there's an airbag mounted under the glovebox.
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.Dropping glove box is pretty simple - there are plastic clips located on the inside "ceiling" of the glovebox (which act as retainers). Push the glove box 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.
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.
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.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.

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.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.

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....but disconnect the battery before going any further--there's an airbag mounted under the glovebox.
