Upgrade your engine’s airflow with the aFe POWER 46-39112 90mm Throttle Body and Adapter Kit. Designed to replace the factory 80mm throttle body, this performance-focused assembly helps increase airflow, horsepower potential and throttle response on compatible Dodge Challenger, Dodge Charger and Chrysler 300 applications equipped with 5.7L, 6.1L or 6.4L V8 engines. Performance improvements may become more noticeable as additional engine and intake upgrades are added.
The kit includes a precision-machined adapter constructed from strong, lightweight 6061-T6 billet aluminum. Its Serrated/Swirl combination design promotes intake turbulence in the combustion chamber, helping break up the fuel mixture for a more complete combustion cycle. This design is engineered to support improved horsepower, torque and throttle response while maintaining a clean, durable appearance. The 90mm bore provides increased airflow capacity compared with the original equipment throttle body.
