I have been using this filter since my car reached 50k miles. I have never tried to clean this filter however I instead replace it every 50k miles (I do take it out every 10k to remove dust, bugs, etc). Great product...works fine, lasts a long time. ‘BIG V8 rollin’ down the road; know that K&N doin’ my motor good. I currently have almost 140k miles on the car; when I take it to the dealership for service and they see K&N, they don’t even to check the filter. I think that says it all

The K&N air filters are as good as advertised.  I installed one in my 2007 Nissan Armada and the other in my 2008 M-45X.  I automatically noticed an increase in vehicle power which as you probably already know they both sport a V-8 power plant.  I am definitely going to purchase another for my wife's 2008 G-35X within the coming weeks.
