"This most recent purchase is a pair of K&N filters for the first air-filter change on my new Infiniti G37S. (This model has two separate air-intakes for better breathing).
I've been using a K&N filter on my 2000 Miata for ten years now (and 90k+ miles), and it still looks brand new. Use the K&N cleaner and re-apply K&N oil to the filter about every 15k miles and you are 'Good-To-Go'! These filters pay for themselves by the second cleaning and you never buy another air filter for that car...EVER!
Thanks for a great product; I recommend K&N to everyone!" —Curtis E from Humble, TX bought a K&N Air Filters for a 2009 Infiniti G37.
