I like my K&N fipk... (don't like K&N's drop in element)
not really caring what the haters do or think
I used the original element for 12 years.
have never purchased another filter element for my junk during that time.
the original element developed a little dry rot (avoidable).
so I asked K&N for a replacement and they shipped that NCTM
so their lifetime warranty works great.
as well... I still have my oem AB/fuzzy w DP mod.
is sometimes installed when I know I'll be rolling wetter trails.
otherwise the fipk resides most always.
I've saved some money over the years
by not needing to purchase replacement filters.
I'd ruin a stock filter (oem AB) in just a weekend
is a 4X that gets used off road often
btw, paid $ 120. for my fipk back in the day.
