The aFe Silver Bullet throttle body spacer kit for Nissan 370Z VQ37VHR (2009–2018) includes two billet 6061-T6 aluminum spacers to work with the VQ's dual throttle bodies. The Serrated/Helix combination design creates controlled air turbulence in the intake manifold to increase combustion chamber air pressure, reduce intake whistle, and improve low-end power and throttle response. The kit uses factory mounting locations and includes gaskets for straightforward installation.
