Brand new, it comes with a blueish paper filter; compared to the yellow oem paper one.
I already had a K&N filter coming in (in fact, its in my mailbox as we speak) to put on my OEM box and just wanted to be sure i'm still gonna use it in the PI.
If I knew I would run 4 different intakes setup in 10 days, I would had liked to do some CFM testings! We're gonna have to go with my butt dyno on that!
