Cabin Air Filter DIY

Step One: Locate the hood latch release lever under the dash on the left side.




Step Two: Open hood and locate the Cabin Air Filter area.




Step Three: Take a medium flat head screwdriver and gently pry the inserts out from the center of the plastic tabs. Caution need to be used at this point, as these little plastic pieces are slippery and tend to jump out of the hand.




You will remove 6 of the plastic inserts




and then remove 6 of these large plastic tabs




Step Four: Gently lift the plastic cover up and remove the dirty Cabin Air Filter. Grab at a corner and pull gently.




Step Five: Place your new Cabin Air Filter back in place. Make sure the filter is pointing in the proper direction when you re-install the new one, there will be air flow arrows on the bottom of the filter. The instructions show the filter being flexed buy both hands, from left to right into a soft -S- shape while lowering into position. The filter is flexible, but caution needs to be used as it will separate on you. Remove any debris that's visible. Place the bottom of the filter as far down as you can get it, and then gently slide the top of the filter into place.



Here's a picture of the new vs the old filter. It should be changed every year.




Step Six: Place all of the large tabs back into place




Step Seven: Place all of the middle inserts back into place




Step Eight: Step back and admire your work

Please make sure the area is clean and free of debris.

Ensure nothing is in the drain tube located on the right side in the pic below.
















I choose Napa / Wix Cabin Air Filter Replacement Part Number 9248.

I always wondered where that cabin filter was. In my previous G35, it was behind the glove box which required slightly more work than this. Thanks for taking the time to make this easy DIY.

Very good SRG. Dang, I thought it was ok to wait 2 years, but that filter is dirty. How many miles on that filter of yours? This month my car is two years old with 18k miles.

That filter has 2 years and 40k on it. Kinda shocked me when I pulled it out and it was almost solid black. I've put more miles on similar filters before and they didn't look as bad.

I'll be changing every year from now on at a minimum.

I'll take a pic of mine when I get to change it. Just for mileage comparison. :)

try an ozone emitting air purifier. Somehow ozone kills off stuff like that. Look up Alpine Air Purifier...

Be careful of the ozone emitters. Yes it will kill microbes but when you get into your car on a hot day you will most likely be 2 to 3 x your OSHA exposure limit. Also, they won't last a year. Now let's say you want to get rid of some lingering smell or smoke damage, I think it's friggin cool how it works.

Just a little FYI.

FYI- Napa currently has all filters on sale for 40% off for this month only. The cabin air filter is $39 during the sale. I also picked up a couple Napa Gold oil filters which were only $3.50.

3 more things to add to this
make sure the filter is pointing in the proper direction when you re-install the new one
there will be air flow arrows on the bottom of the filter(they must point to the HVAC)
also, the filter is flexible/bendable making it easier to fit inside the compartment.
Make sure to clean all debris away from cabin filter area(leaves, dirt, etc...) before installing new filter
BTW, great write up

Great write up. Thanks for sharing this info. Definitely time to look at changing my filter. Almost 2 years old and just over 16K on the clock.

This is a great deal as my sh*tty dealer wanted 78 for the OEM part. I'm all over the napa gold oil filters, thanks for the tip.
