Key Features and Specifications

The GrimmSpeed StealthBox Cold Air Intake boasts an array of impressive features that set it apart from the competition. Its hybrid design ensures maximum airflow, while the air straightener ensures accurate MAF sensor readings for optimal performance. The MAF sensor is located inside the heat shield, keeping it isolated from the engine bay's heat. Additionally, the custom reusable high-flow air filter features an integrated velocity stack entrance, which smooths incoming air for a cleaner, more efficient intake process. The StealthBox heat shield not only enhances the engine bay's appearance but also shields the intake from unwanted heat, further optimizing performance.
