Gives your STI More Airflow and Improved Response

Your awesome Subaru STI is hungry for more power, but to maximize your gains from tuning and other modifications, you’re going to need to do better than the factory intake. The COBB SF Intake Kit for 2015-2018 STIs maximizes your Subie’s inlet airflow to feed your STI’s turbocharger and motor with all the air it needs to make some big power with the right combination of tuning, custom tuning, or other aftermarket parts and accessories. This version of the COBB SF Intake comes standard with a complete air box assembly that helps the COBB system quieter than open-air intake kits without overly harming airflow. The COBB SF Intake Kit will require a COBB OTS tune or a custom tune from a reputable STI tuner for proper installation.

High-Quality Intake Kit with Reusable Air Filter and Enclosed Airbox

COBB carefully and precisely designed their SF Intake Kit for the Subaru STIs to provide a huge improvement in airflow over stock in a drop-in package. The SF Intake is built around a CFD-designed velocity stack that leads into a specialized air straightener before passing through the MAF sensor to provide accurate readings and eliminate dead spots caused by turbulence. The velocity stack and MAF housing are made out of a plastic composite that resists heat soak to help keep initial inlet air temperatures down over metal intakes. Each SF intake comes with a pre-oiled, conical air filter with your choice of either a blue or gray filter media. The filter is reusable with proper cleaning and re-oiling and brings in a large volume of air while improving filtration over stock. The filter is housed in a complete air box assembly that’s designed for use with the factory inlet scoop so that the intake stays quieter than open-element designs without losing out on overall airflow. Each kit comes with all its necessary hardware and instructions. This kit will require a COBB OTS tune or a custom tune from a reputable tuner

Requires tuning: this intake kit requires tuning for proper operation and to avoid engine damage. COBB offers an OTS tune for this intake on their Accessport V3 device, though custom tuning from reputable Subaru tuners on other devices can also be used.

CARB Approval: this intake is only CARB approved on 2015-2016 STI models when using COBB’s OTS tunes. COBB does not yet have CARB approval for 2017-2018 STIs, and custom tuning is not CARB-approved.
