All Silver Bullet Throttle Body Spacers are precision machined from 6061-T6 billet aluminum for lightweight, high strength, and perfect fit and finish. It is black anodized for a durable long-lasting finish. This premium wrapped coupling is constructed of high temperature silicone which meets or exceeds SAEJ20 Standards. This Silver Bullet throttle body spacer uses all factory mounting locations and a gasket ensuring a proper seal and a hassle-free installation.
