thing I never liked about my TiiCo was the air filter. The way
it fit in its can left very little room for air to actually get
into and through the filter. I decided to solve the issue by replacing
the paper filter with a K&NŽ air filter. The K&NŽ filter
has two major advantages over the "stock" filter.
It can be cleaned and reused, instead of needing to be replaced.
Just by its very nature, it breathes better than the stock filter.
my application, I was able to get even better airflow because
of the filter I chose. Instead of going with a direct cylindrical
replacement, I chose a truncated cone shape. Because it's cone
shaped instead of cylindrical, it had more clearance between it
and the wall of the enclosure so more air could get to the filter.
Another thing which let the new filter breathe better was the
fact that the end of it also had filter element to allow air to
go straight into it instead of having to go around to the side
of the filter.
K&NŽ wasn't a direct fit, though. I did have to modify the
filter slightly. the "flange" at the bottom of the filter
was a little too small to fit over the neck of the stock filter
mount. I solved this problem by cutting off the flange and widening
the hole on the bottom of the filter so it would go over the neck
of the filter mount. A word of warning, however. Don't remove
too much material from the bottom of the filter because you still
want it to be a tight fit on the neck of the mount.
This shows the side by side comparison of the filters.
This shows the "end on" comparison of the filters.
This shows what I removed from the K&N to make it fit
in place of the stock filter.
