Description

The GrimmSpeed StealthBox Cold Air Intake for the 15+ STI is a hybrid design combining elements from previous WRX intakes with the StealthBox heat shield. It features a custom reusable high-flow air filter with an integrated velocity stack, an air straightener for accurate MAF sensor readings, and a heat shield to isolate the MAF sensor from engine bay heat. This product is made in the USA, has a 30-minute installation time, and requires tuning.
