Improve intake airflow and throttle response with the aFe Silver Bullet Throttle Body Spacer Kit, part number 46-36004. Designed for select Nissan Armada, Nissan Patrol (Y62), Infiniti QX80 and Infiniti QX56 models equipped with the 5.6L V8 engine, this throttle body spacer uses a serrated and helix combination to create controlled air turbulence inside the intake manifold. The resulting airflow effect helps increase air pressure in the combustion chamber for improved horsepower, torque and throttle response. The combination design also helps reduce intake whistle commonly associated with helix-only throttle body spacers and is covered by U.S. Patent 07055513.
Manufactured from precision-machined 6061-T6 billet aluminum, the Silver Bullet spacer provides a lightweight, high-strength construction designed for a precise fit. Its durable finish complements the engine compartment while supporting reliable performance in demanding driving conditions. The kit includes the required gaskets and uses factory mounting locations, helping simplify installation without requiring extensive modifications to the intake system. A silicone coupler accommodates expansion, movement and vibration for a more secure connection during operation.
When properly installed, this aFe throttle body spacer is engineered to produce gains of up to 6 horsepower and 8 pound-feet of torque, while enhancing engine response under acceleration. Installation is designed to be straightforward for qualified installers using standard tools and the included components. The spacer is intended for select 2017–2024 Nissan Armada, 2010–2026 Nissan Patrol (Y62), 2014–2024 Infiniti QX80 and 2011–2013 Infiniti QX56 models with the 5.6L V8; verify vehicle application before ordering.
