I think our 8.2Ls hold 16 quarts with two napa 1060 filters. If you use the larger 1794s you will need to add 2 more quarts. We change ours at 8000 miles. I cant remember the air cleaner number. I'll see if I can look it up tomorrow.
Sounds about right. Thanks for the info...if you happen across that air filter, let me know, otherwise I'll make NAPA earn their money and find it for me!
