A'PEXi Induction Box (Subaru WRX 02-07 / STi 04-07) 517-F001

The APEXI Aluminum Induction Box effectively shields the intake filter element from power robbing heat caused by turbocharged engines and extreme under the hood conditions. By fully enclosing the filter element and directing the intake air charge away from the heat soaked engine components, the APEXI induction box helps prevent the ingestion of hot, preheated air from within the engine compartment. This reduction of intake air temperature promotes more efficient combustion, which in turn creates better performance and increased reliability. All components are manufactured by APEXI to the highest standards to ensure precise fitment and maximum performance.
