Hey everyone. Before my Amsoil Nanofiber 4" x 9" cone filter I had a KN panel filter. After about 10K miles of driving with that the entire inside of my throttle body collected a nice film of sludge. I installed my Wizair a few weeks ago and used a 4" x 9" Spectre Oiled cone filter. It was cheap and oiled, I'm assuming it was close in performance to a KN. Well I did some research online and read about Amsoils "Nanofiber" filters. They are supposed to get 25% better filtration and still maintain excellent flow. I bought one and installed it. My supercharger is significantly louder and the car is more responsive with the Non-oiled Nanofiber Amsoil filter. The US military has been using Nanofiber filtration in the M1A1 Abrams take for more than a decade. Its about time we got to put it in our cars!
Anyone else used one? They kicka*s!
