I have used your filters in all of my many vehicles, including Honda Goldwings. I find the filters are excellent (I have noticed I can get your filters at Walmart a few dollars cheaper, but have always ordered direct from you guys). Keep up the good work.
John Miller, Waldorf, Maryland
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.
