Review APR Throttle Body Inlet System Adapter 2.5t fits EVO 2019

The APR MS100198-A Throttle Body Inlet Adapter is a high-performance component designed for select 2019 Subaru WRX and STI models with the 2.5L FA20DIT and FA24DIT turbocharged engines, specifically those equipped with the EA855 engine management system. This adapter is manufactured by AP Racing, a renowned name in the automotive industry, known for their expertise in producing top-tier racing components.

This throttle body inlet adapter is an essential upgrade for those seeking to optimize the airflow and enhance the overall performance of their Subaru. The adapter is designed to replace the stock inlet with a high-flow, larger diameter design, allowing for a more efficient intake system. This results in improved throttle response, increased power output, and smoother engine operation.

The APR MS100198-A Throttle Body Inlet Adapter is CNC-machined from billet aluminum, ensuring a precise fit and exceptional durability. The surface is then anodized for added protection against corrosion and wear. The adapter features a large, 63.5mm inlet diameter, which is significantly larger than the factory 57.8mm diameter. This larger inlet diameter reduces the restriction in the intake path, allowing for a more efficient airflow to the engine.

The adapter also includes a high-flow, 4-layer, synthetic air filter to ensure clean air enters the engine. This filter is designed to provide excellent filtration efficiency while maintaining a low restriction. The filter housing is equipped with a unique, easy-to-access design that allows for quick and convenient filter changes.

The APR MS100198-A Throttle Body Inlet Adapter is designed to work seamlessly with the stock airbox and intake system. Installation is relatively straightforward and can be completed with common hand tools.
