Nissan Armada Throttle Body Spacer - aFe - Silver Bullet, Serrated/Helix - `17-`24 is a precision-machined throttle body spacer for 2017–2024 Nissan Armada V8 5.6L applications. Designed to fit using all factory mounting locations, it improves intake airflow and throttle response without complex modifications.

The Serrated/Helix design creates controlled air turbulence in the intake manifold to increase air pressure in the combustion chamber and reduce the intake whistle common with helix-only designs (US PAT 07055513). Machined from 6061-T6 billet aluminum, the spacer is lightweight, strong, and finished in a durable Silver Bullet surface. The kit includes gaskets and a silicone coupler to allow for thermal expansion, movement, and vibration, making installation straightforward for experienced enthusiasts and professional shops alike. Road-proven performance gains are achievable while retaining OEM mounting points.
