Motordyne Nissan 350Z 1/2″ Basic Plenum Spacer

This Motordyne spacer is 1/2 in. thick. It is stealth and can easily adds 12HP-14HP. The plenum spacer can be used for maximum performance enhancement. It also adds a substantially deeper 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. All Motordyne melt proof plenum spacers come with pre-attached, high quality gaskets.
