This k&N intake is badass I used for about 1 month and then went with a blue air filter it will fit a M8 will not change your tune but will gain horsepower everything's in perfect condition and I'll throw in a $50 labeled rain sock
(Also still have box and instructions)
PS they retail for about 159 to $200 now they used to retail about a year ago for $299 when I bought it so $65 is a good deal plus I'm throwing in the free rain sock that was $50 that's labeled k&n
