Thanks Sascwatch, I recall reading that in the manual earlier this year, but you reminded me where it is - thanks!
Do you think the airflow stayed the same or decreased?Not bad. It's working well so far. No complaints
Good call. I definitely wouldn’t use an N95 unless you have major health issues. It really hurts the air flow.The dealer wanted to change my cabin air filter, it was almost $50 bucks, must have been the new N95 filter, it was really dirty after 2 years and 60,000km, the manual says to change yearly or at every 20,000km. I don’t drive on dusty roads often and our rainy fall and snowy winters are long, so no dust during those seasons, I bought an aftermarket for $20.
I get more airflow with the K&N. You can run the system and inset/remove and try for yourself. No filter was best airflow, Probbly would be fine too depending on where exactly the inside sucks from.I’d like to get something with minimal restriction. Maybe the k&n would work
This is exactly what I have done. Put the AC on and pulled/inserted the filter to compare. Without the cabin filter, it’s like I have a “9” on high instead of “7”. It’s just as good as other vehicles without it installed. Seems like maybe the filter is undersized for the blower, idk.I get more airflow with the K&N.

I then drove for about 30 minutes with no filter and loved the results.
Not sure where the intake on recirculate is, but I think the inlet is at the cowl for outside air.
If k&n is the best flowing I guess I’ll have to go that route.
Thanks
I had been using this one, but if there’s another that allows more air to flow I’d me willing to try itWhen I inspected my filter yesterday, I could see the blend door and actuator just a few inches above the filter. The air inlet for recirc is high in the dash, behind the upper glove box area.
I picked up this STP filter for ~$20 from autozone yesterday evening. Probably get it installed today and I’ll report back with quality and flow comparison. Ram dealership wanted $50 for a new OEM one. OEM must have gold frame or something
Thanks for the review. I would’ve thought more pleats would be more restrictive since they are so tight.Just installed the STP. Initially it looks more restrictive than the OEM, however it has more pleating which means more surface area for airflow. Dimensions are exactly the same. I tried performance with old filter, then no filter, and finally with new filter. I also used a decibel meter during each test.
I felt a bit more airflow with no filter in place, however the noise was very annoying. Sounded loud, hollow and echoed. Noise was 67.8 dB with no filter. I felt no noticeable airflow difference between OEM and new STP filter, however I appreciated the softer quieter noise level of the STP. OEM was 65.8 dB, and STP was 63.8 dB. It always bothered me at how loud and hollow the AC system sounded compared to other vehicles I’ve owned. Airflow seems the same but now it sounds like I’ve been moved into a soundproof room with all the acoustic eggcrate foam in the walls
Wish I would have changed to this STP years ago!
The dB images below were taken in the order of OEM, then no filter, and finally with new STP.
If you want more airflow don't get one with activated carbon, likely to just build up sooner over timeI had been using this one, but if there’s another that allows more air to flow I’d me willing to try it

Thanks. I’ll give that one a shot.If you want more airflow don't get one with activated carbon, likely to just build up sooner over time
The K&N ones are washable so you just buy it once too, clean it whenever you want.
Onsale currently for $36, I pay $42 for mine from Amazon
More pleats equal more surface area.Thanks for the review. I would’ve thought more pleats would be more restrictive since they are so tight.
