85mm Throttle Body

The AFE POWER 85mm throttle body (model 46-39113) is a direct-bolt upgrade designed for automotive enthusiasts looking to enhance engine responsiveness and airflow efficiency. This component replaces the factory throttle body, optimizing volumetric efficiency at higher RPMs. It is suitable for both naturally aspirated and forced induction setups.

Engineered with precision CNC-ported internals, this throttle body is designed to improve airflow characteristics while maintaining smooth air delivery across the RPM range. The larger bore diameter increases peak airflow capacity, which is essential when other components like the intake manifold and fuel injectors are optimized. Its cast aluminum construction ensures durability and thermal stability.

This upgrade is particularly beneficial for owners of turbocharged, supercharged, or high-output naturally aspirated engines. The direct-bolt design guarantees compatibility with existing intake manifolds and engine management systems, allowing for easy installation without the need for custom tuning.
