I ordered a K&N a month ago. It still hasn't come. I'll pull out the digital caliper and measure every dimension and compare to oem when it comes.
did you dbl check the inner diameter for the rubber grommet/seal? seemed to me that the K&N is slightly bigger... i did return mine.
Is the K&N part number the same for the 1199 and 1299? Sometimes aftermarket companys are slow to react to changes. K&N is usually the exception
Very soon (installing it) - what are your concerns? Several 1199 owners use them
