Motordyne 1/2" Iso-Thermal Plenum Spacer Kit G35/350Z
(Customer will loose the strut tower bar for 350z)
This stealth modification adds 12HP-14HP and reduces the effect of power robbing heat soak. This plenum spacer can be used for maximum performance enhancement. It also adds a substantially deeper induction growl under the hood. The 1/2″ plenum spacer is fully compatible with the engine cover but is too large to fit the stock strut bar. With the engine cover in place the engine bay looks completely stock with the only difference being the strut bar is not installed.
