Hi.
I have the urge to squeeze a few more HP out of my Z (04 plate). The problem that i have is that i have read somewhere, that by installing a Plenum spacer and a pannel filter you can gain a few more HP.
On the other hand i have also read that because the Z has a specific type of ECU and air folw meter they would recognise the changes and adjust things accordingly which would result in no gains at all.
I would appreciate any advise at all, and if any one could back up the claims with power print outs even better.
Thanks Rothers2901
