The intake makes a sucking sound whenever I push on the gas. More gas, more sucking. Its a 2009 JCW. Is this normal? I don't recall the sucking sound until just recently. I looked over the miles of piping under the hood for the intake but can't see anything that seems out of the norm. It does look like there are sections that are restricted or could create a lot of turbulence. Anyone else have the sucking sound?
