COBB SF Blue Intake and Airbox Package 2015-2018 STI

Setting the standard for MAF style intakes with a velocity stack, airflow straighteners and composite body for ultimate performance. Feed your SF Intake cold air using the Subaru factory snorkel. The SF Airbox turns your SF Intake on your 2015+ STI into a cold air intake with OEM looks and fit.

This intake and integrated airbox looks great and combines the benefits of a short ram and cold air intake without the downsides. It features unique design elements to maintain optimal flow and minimize turbulence that can cause engine management issues. A custom conical cloth filter connects to a CFD-designed velocity stack and an air straightener grid that smooths airflow past the MAF sensor for accurate readings, eliminating "dead spots" found in other intakes. No other Subaru intake uses these elements. The one-piece high-temp plastic composite design saves weight and rejects heat better than metal, keeping intake temps cooler. The SF Air Box adds cold air intake benefits by enclosing the SF Intake and blocking hot engine bay air, while also preventing rainwater ingestion—unlike in-fender intakes.

Note: Tuning required for 08+ Subarus; COBB offers Off-The-Shelf Maps via the Accessport for easy setup—just install, flash, and go. See the Subaru Accessport Map Database for available SF Intake Maps.
