I know there is a lengthy thread on this subject but it got
confusing so I'm asking just for C43 owners that use K&N
filters to respond. I've got (2) brand new filters sitting on
my work bench and I need to know what to expect after I
install them or if I should install them. Are the problems with
these only after they have been cleaned and re-oiled or
right out of the box? I look to the wisdom of my favorite club
for the answer. Thank you in advance.
