stock air filter engineering specifications

[DLeno]

Where can I find the performance specs of the stock air filter? stuff like flow, restriction, filtration efficiency at condition x, y, and so on.

I have not looked myself but a fella in this thread mentioned its printed right on the filter.

yea, I got 675. 21 cfm at 14. 05 inches of water. Havent actually looked at mine either . but anyway I'm looking for filtration specs too -- like % efficiency at particle size x, or some reference to SAE fine dust test or SAE course dust test.



This is related to the whole PG-7 question, and the desire to meet or beat the factory filtration efficiency with an after market filter. But no one seems to know what the factory spec actually is. They say 99% but I dont' know if that means 1 marble out of a 100 gets in the engine, 1% of 20 micron particles, or what.

Maybe since the FleetGard #AF26106 is a direct cross for the factory filter you could get the data you want from FleetGuard.

You're a gentleman and a scholar. Here's the data I got back from Fleetguard:



Part No : AF2610600

Part Function PRIMARY/MAIN







OVERALL LENGTH 10. 906 in



OVERALL HEIGHT 2. 783 in



OVERALL WIDTH 9. 921 in







FILTRATION, MECHANICAL SPECIFICATIONS AND TEST STANDARDS







CAPACITY 504. 4 g SAE J726



FINAL EFFICIENCY 99. 56 % SAE J726



CLEAN ELEMENT DP, MAX 4. 66 in H2O



RATED FLOW 452 ft3/min



TERMINAL DP 16 in H2O

Hrmm, where on the Fleet Guard site did you find that data?

Would be interesting to compare to the popular BHAF filter though I am not sure what that part number is.

I sent them email.



to my surprise and pleasure they responded with real data. what a concept. I called DC and they sent me to the dealer. I called the Dealer and they sent me to Mopar. Mopar doesn't accept calls from customers so I called the dealer service manager. he said they just don't have that kind of information and they can't even get it either.
