Hey just wondering whats the life time on a injen air filter?
how often should it be replaced?
I just removed mine for the first time for cleaning (been a year) as I have to remove my front bumper to remove the filter and it is quite dirty...
so I blew it off with an air line and am going to clean it up with K/N filter cleaner...
anyone know the life expentance of there filters?
Thanks!
