Cabin air filter

[rjgvt]

I haven't seen to much about replacing the cabin air filter. I replaced the filter on my last truck twice a year as it always had stuff in it from parking under trees when hunting, etc. I used the Fram TrueAir filters from Walmart as they were economical and fit good. 

 

My truck is 16 months old and has over 17k miles on it so I decided to change the cabin air filter. Went to Walmart and no stock on the Fram CV11966 filter. Not in stock at the two Walmarts in the area. The AC Delco CF185, P/N 13508023 is around $55 at online GM parts websites and assume that is the cost at the dealer. Found the AC Delco filter at our local O'Reilly Auto Parts store for $26.99 + tax. Not a steal but is OEM and fit perfect. And made in USA. For the price I'll probably change it once or twice a year. No tools required to take the glovebox out. My last truck needed a torx driver to get the glovebox out.

 

Old filter was blackish and had no debris on it.

I purchase the engine air and cabin filters from Rock Auto for my '23 gas.  

 

Air:  ACDELCO A3244C $26.89 -  I believe the C indicates "carbon" filtration vs standard which is not carbon

Cabin:  ACDELCO Gold/Professional CF1184C is $16.28 (Carbon)

 

Interesting:

The FRAM CF11966 cabin air filter is $3 more than the ACDelco Gold

The AC Delco air filter is orange color foam/rubber portion (Fram?), but so are the Baldwin, WIX, and a few others.

 

NOTE:  There appear to be three versions of ACDelco cabin filters....Standard particulate, carbon, electrostatic

I run carbon and change every oil change. I have recirc on 99% of the time.

After reading a report about CO2 levels reaching above 5,000PPM when driving on recirculation, I rarely ever use it anymore.

 

If you are running recirc 99% of the time, why change the cabin filter so often.

Why would you need or want a carbon engine air filter and where did you read that the C denotes carbon?

There isn't a "carbon" engine air filter.  There is carbon cabin filters.  The "C" on the cabin filter designates carbon.  

 

The A3244C is the high capacity engine air filter for gas T1 pickups.  Its the optional filter on the 1500s, its the standard filter on gas HD.

I believe it is noted on RA website where these air filters are featured.

 Thanks for the clarification.  I assumed fine the cabin filter had a c at end of part number and signified carbon, it won’t be same for sir filter.  After thinking about it, carbon for engine air filter doesn’t make sense.

 

BTW… what is T1?

T1XX = The current generation of GM truck chassis code name.  

 

2019-current (2020-current HD) = T1XX

 

2014-2019 1500 and 2015-2019 HD = K2XX

 

2007-2013 1500 and 2007.5-2014 HD  = GMT-900

 

1999-2007 1500 and HD = GMT-800

 

etc...

I ordered a couple of the carbon cabin filters, CF1184C, from Rock Auto. They arrived and thought it was funny that they were made in China. The plain AC Delco cabin filter that I took out and the replacement were made in the USA.
