The last three posts are spot on.

The last three posts are spot on.
the 180hp (2.0ltr) DW engine revs to about 4.5k revs,
So with the turbo going at full chat sucking in, without doing the calc ~2.8ltrs
The Focus ST & RS I suspect (2.0ltr? not looked) are doing 6.5 - 7k revs.
So if the same filter element is fitted as you said, easily cope with the Kuga.
Ford put it in a housing for a reason, as a plenum chamber I suspect
and I hope??, done tests for cold, hot, wet & dusty conditions.
K&N reply with - get some oil filter paper, in a gauze, and make it fit - then give it a part No.
I still think a quality new paper one every 10 - 12k miles must be better than
squeezing 25k out of a K&N before re-oiling. My OE Mahle one was definitely past it best at 17,600 mls.
