About 5 quarts
I have a rubicon 2004 the oil capacity is 5.2 to 5.5 quarts. You have to put 5 quarts in and crank the 4 wheeler and let it run for 1 minute and check the oil as soon as you turn the engine off to see if you need to add .2 or .5 to your rubicon. The ? is about a Honda Rubicon ATV.
The 2006 Rubicon holds 4.9 qts when you change it. It is for both the engine and transmission.
Yes it seals so all air has to come thru filter
