Post-Plenum Knock NOT related to Front Strut.
Hey All,
I just recently installed an AAM Angled Plenum Spacer on my 2006 350Z. Installation went smooth, problems emerged after I went to go test drive it. At higher speeds and RPM, there’s a distinct knocking sound that concerns me. I read a few other forums and they all said “front strut” so I raised it, raised it some more, and eventually took it off (don’t wanna hear ‘yOuR cAr WiLl RuN LiKe cRaP’) and still get the noise. Any thoughts on what might be causing this? Your input is greatly appreciated.
