You've been asking for this bad sally for a while and it's finally here. The intake the for the 15+ STI can be thought of as a hybrid of the tube and filter used in the 08-14 WRX intake and the Stealthbox heat shield used in the 2015+ WRX intake. Small design changes were made, but the overall fit and performance is approximately the same.
Quick Specs
Hybrid Cold Air/Short Ram Design - Combining the advantages and eliminating the negatives of both traditional intake designs
Air straightener - Dimensionally mimics the factory configuration for accurate MAF sensor readings
MAF sensor location - Inside heat shield, isolated from engine bay heat
Custom reusable high flow air filter - Integrated velocity stack entrance smooths incoming air
StealthBox Heat Shield - Sleek, unique design looks KILLER in your engine bay and keeps the heat of the engine bay from affecting performance
Made in the USA - Right here in Minnesota, in fact
30min Installation - Extremely simple with our written and video guides

The GrimmSpeed engineering and manufacturing teams are known for designing and producing products that use high quality materials, offer perfect fitment and superior craftsmanship and are durable. These intakes are no different and feature the proven performance of the 08-14 WRX EJ motor intake (third party results coming soon) with a look and feel that set it apart from the competition.
