aFe Silver Bullet Throttle Body Spacer (46-36002) boosts airflow, torque, and efficiency for 2005–2009 Nissan 4.0L V6 models with durable billet aluminum design. This precision-machined spacer is constructed from high-quality T-6061 billet aluminum and designed with a unique serrated/helix pattern that increases air turbulence at the intake manifold. This turbulence helps improve throttle response, fuel efficiency, and power output while eliminating the whistle commonly found in helix-only designs. The spacer increases the volume between the throttle and the cylinder, improving volumetric efficiency and combustion performance.
