MOTORDYNE 1/2"BASIC PLENUM SPACER KIT G35/350Z

MD-12B

This stealth modification adds 12HP-14HP and is the simplest to install. This 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.
