9 years and 25K miles

on the stock air filter.  The new K&N maintenance doesn't come around for 50K more miles- at this rate I won't need to look at it until 2027.


It does seem to run a lot better now!

May get better mpg now that more air will be mixed with the gas.

My experience says you may want to check and clean the new K&N more often than that. Since it is lightly oiled it traps more dirt and even though you don't throw it away you may feel the need to clean it more often.
