Nissan Patrol Throttle Body Spacer - aFe - Silver Bullet - `17-`19. This CNC-machined Silver Bullet throttle body spacer for the Nissan Patrol (Y61) I6-4.8L is designed to alter intake airflow just before entry to the engine, improving throttle response and drivability in a straightforward bolt-on package.

The aFe Silver Bullet spacer uses a unique serrated/helix entry to generate controlled turbulence at the manifold while minimizing the high-pitched whistle common to helix-only designs. Constructed from durable 6061-T6 billet aluminum, the spacer is precision-machined for a consistent fit and finish. According to aFe, the Silver Bullet design increases air speed into the intake, which can translate to better throttle response and measurable gains; reported improvements include up to +7 HP and +13 lb-ft of torque on compatible setups. This part is intended for owners who want a reliable, reversible modification that complements other intake or tuning upgrades.
