Add a swirl to the incoming air charge with the aFe Power Silver Bullet Throttle Body Spacer (P/N 46-32005, also written 4632005). This billet spacer installs at the throttle body just prior to the air entering the engine, where its serrated/helix entry is designed to create turbulence in the airflow — which aFe says helps increase horsepower, torque, throttle response and fuel efficiency — without the annoying whistle found in helix-only designs. It fits the 2005-2021 Chrysler 300, 2007-2009 Chrysler Aspen, 2011-2025 Dodge Durango, 2009-2010 Dodge Ram 1500, 2010 Dodge Ram 2500, 2011-2021 Jeep Grand Cherokee, 2011-2024 RAM 1500, 2019-2024 RAM 1500 Classic, 2011-2018 RAM 2500 and 2011-2018 RAM 3500, all with the V8-5.7L engine.
