aFe Silver Bullet Throttle Body Spacer Pair for Select 2008-2020 Infiniti & Nissan (V6-3.7L)

Fits select 2008-2020 Infiniti G37, Q50, Q60, and Nissan 370Z (V6-3.7L).

Improve the low-end horsepower and torque of your VQ37VHR engine with the aFe Silver Bullet Throttle Body Spacer. This kit includes two spacers to accommodate the dual throttle body design found on high-performance Nissan and Infiniti V6 powerplants. Precision-machined from 6061-T6 billet aluminum, these spacers are designed to optimize the air-fuel charge entering the combustion chamber.

The Silver Bullet features a patented Serrated/Helix combination design (US PAT 07055513). This unique geometry creates air turbulence within the intake manifold, increasing air pressure in the combustion chamber for improved throttle response. Unlike standard helix-only designs, this serrated-helix hybrid significantly reduces the "intake whistle" often associated with aftermarket spacers. Installation is straightforward, utilizing factory mounting locations and including gaskets for a reliable seal.

• Construction: Precision CNC-machined 6061-T6 billet aluminum for high strength and perfect fitment.
• Optimized Airflow: Patented Serrated/Helix design increases air turbulence and intake pressure.
• Reduced Noise: Engineered to minimize the whistling sound common in other helix designs.
• Complete Kit: Includes two spacers, gaskets, and all necessary hardware for dual throttle body applications.
• Part Number: 46-36007
