I bring up the intake because there was a thread on the link forums about placing the filter in the smic location. They were receiving significantly less
knock after moving the filter there. I did it at the same time as I switched to e85, so I can't say 100% or not if it helped. But those 2 things are what I did and I ripped her around the neighborhood a good bit and didn't have any knock.
