Well I'm gonna throw some Denso IKH24's in there and see if that completely eliminated the random knocking. I prolly should be running them anyway at my power level (~300whp on a mustang dyno). Doing a full AMSOIL change (oil,trans,tc,diff) at the same time. I might at that samco intake while I'm in there since I'll be under the hood tweeking/cleaning a few things anyway. Do you guys think that would be wise? Or would it require retuning (which I can't do until I get a wideband).
