aFe Silver Bullet Throttle Body Spacer (46-35002) boosts airflow and throttle response for 2007–2011 Jeep Wrangler JK 3.8L engines with billet aluminum design. Made from precision-machined 6061-T6 billet aluminum, this spacer features a unique serrated/helix design that promotes turbulence in the intake airflow. This turbulence helps break up the fuel mixture for more complete combustion, leading to better throttle response, increased horsepower, and improved torque. Unlike traditional helix-only spacers, the serrated edge reduces the annoying whistle effect while optimizing performance.
