Ok I have a 2018 Hellcat, I want to replace the stock air filter with a higher flow filter. Some have said K&N others have suggest a B-woody. Which after market Air flows better than stock.

Here's a nice post, I don't know where the numbers come from. I believe the stock filter flows very well. Some swear by the Green filter though

The HC filter is fantastic, and is what us po' folk upgrade to. You're likely not outflowing it unless you've been modding.

I datalog the hellcat filter and a K&N drop in filter and the K&N out flowed the hellcat filter so I stayed with the K&N filter. If my supercharged v6 can see a gain I can only imagine a bigger gain of airflow on the hotter hellcat engine.

I removed the factory Hellcat filter and installed a K&N drop in filter.

Bottom line I have more airflow into the engine via the K&N filter. So at least in my testing the K&N filter flows more than the hellcat filter.

So here are the numbers

Hellcat air filter:
6800 1324 mg/charge
6500 1334
6200 1380
5900 1403
5600 1406
5300 1426
5000 1480

K&N drop in filter:
6800 1333 mg/charge
6500 1361
6200 1392
5900 1417
5600 1440
5300 1449
5000 1505


I cut and paste the above from my thread long ago, All thru data logging recording the air flow mg/charge on the tuner. Not much more to share. diablosports trinity

Appreciated. Apologies for not being more specific and asking for the testing methodology ,and results, but you checked all the boxes.

Given that info, I'll still lean towards the filtration the HC filter offers vs the airflow properties (removed at the track), but it's awesome to have data points.
