Overview

The Cobb SF Intake + Airbox is a black intake system designed for the 2015-2018 Subaru WRX STI. It combines the performance benefits of a short ram intake with those of a cold air intake.
Show original supplier description
Designed for the 2015–2018 Subaru WRX STI models, this system effectively addresses pre-turbo restrictions found in the stock intake. This intake system features a composite intake body and a 16-gauge aluminum airbox, designed using CFD velocity modeling to optimize airflow. The SF Intake system is crafted to maintain optimal flow for enhanced performance while minimizing the turbulence that can lead to engine management issues. It is available in black and is designed as a direct fit for the specified Subaru models.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
