i just checked mine yesterday,looked brand new with NO sign of use at all.
totaly clean.4500 miles
it will be a long long time before i will probably need a replacement.
as i was checking out the original pleated honda filter,i though it was a very high quality membrane compared to most types like this one.
i do run a K&N on my ranger but really dont see the need on my cbr unless it's giving me even more return on my already outstanding mpg.

curious about ecu relationship here, esp as installed
a lv one evoII carbon slip-on which lv state is 'tuned'
to suit our bike thus does not require remapping
or ecu reset.. [bike runs great with neither]

would opening the airbox or strategically drilling it
for [some] increased airflow interfere with ecu
monitoring to suit its typical lean running [?]
if so would ecu reset then be necessary
[or would ecu simply monitor/adapt] ?

[last honda cb750 had k&n pods + 4/1 exhaust
combo which worked very well - no ecu of course]
