aFe Silver Bullet Throttle Body Spacer Kit for Nissan 370Z and Infiniti VQ37VHR, Part Number 46-36007

One of the easiest additions to improve low end horsepower and torque to your VQ37 is the Silver Bullet Throttle Body Spacers. The TBS has both a Serrated and Helix combination design, which creates air turbulence in the intake manifold, increasing the air pressure in the combustion chamber. This design also reduces intake whistle that occurs with other helix-only designs. Kit comes with two spacers to work with the VQ's dual throttle body design. Serrated/Helix Design: The Serrated/Helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber resulting in increased horsepower, torque and improved throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other helix only designs. (US PAT 07055513) 6061-T6 Billet Aluminum Construction: All Silver Bullet Throttle Body Spacers are precision machined from 6061-T6 billet aluminum for lightweight, high strength and perfect fit and finish.

Improve low-end horsepower, torque, and throttle response on select Nissan and Infiniti vehicles equipped with the VQ37VHR 3.7-liter V6 engine with the aFe Silver Bullet Throttle Body Spacer Kit. Designed for the engine’s dual-throttle-body configuration, this kit includes two precision-machined spacers that help optimize airflow as it enters the intake manifold.

Each aFe Silver Bullet spacer uses a serrated and helix combination design to create controlled air turbulence in the intake manifold. This turbulence can increase air pressure in the combustion chamber, supporting improved throttle response and enhanced engine performance. The combination design also helps reduce the intake whistle commonly associated with helix-only spacer designs. Constructed from lightweight, high-strength 6061-T6 billet aluminum, the spacers provide a precise fit and durable finish. The design is covered by U.S. Patent 7,055,513.

Installation uses factory mounting locations and includes the necessary gasket for a straightforward, hassle-free installation.
