It's not just the boxes...it's the elements themselves.
Also note...the boxes actually help in the velocity of the air
entering the carbs.
That is to say...you'll notice the air intake on the box
is the same size as the carb throats. The higher velocity gives
better low and mid range power and helps atomize fuel better.
The K&N's are only really benifical if and when you are breathing more
(bigger pistons or cam upgrades or ported and polished or ...etc or any combo
of the above)
You'll have to thin out the needles (richen the mixture) to compensate for the
higher
air intake volume due to the reduced breathing limitations caused by the lesser
efficiency of the original style filter elelments.
I run Dual open box K&N's on my 18V (+0.020 overbore mild cam upgrade)
I had to go all the way up to AAA needles and heavier air piston springs to get
the entire range of fuel/air mixt correct.

Subject: We Be Tight -- Aircleaners?
OK, while I ponder the possibilities of K&N Filters,
how about this for a totally reversible We Be Tight
set of "fancy" air cleaners:
1. Take apart the 2 stock filter cans.
b. Discard the larger top pieces.
3. Cut 2 wood or metal circles the same size as the outer circumference
of the paper filter cartridges and drill holes for the stock
mounting
bolts.
D. Use the original bolts thru the wood/metal disks, inside the paper
filter elements (using the metal spacer tubes for structural
integrity) and into the carbs.
Wotcher think? Will it work? Wot's wrong with this picture?
