Bob,
Thanks for providing the info to us. I have never played with the K&N open
element before for two reasons. I don't like the sound at high throttle
settings (personal
preference, try listening to it for hours as you tug a boat across desert
out here in Calif). And I am one that believes in ducting cold air to the
engine (1% loss in
horsepower for every 10 Deg. rise in inlet air temp). I prefer the drop-ins
and I am pleased in them (definitely Not as nice looking). Again thanks for
the info, no
better way (for all of us), then a pull.
Frank
