Cobb SF Intake System Subaru WRX 2015-2021 | 745120

Fitment: This intake system is specifically designed for 2015 - 2021 Subaru WRX models. Features: The COBB SF Intake System is an excellent entry - level upgrade for your WRX. By replacing the factory intake and airbox, it significantly reduces pre - turbo restrictions. This allows the engine to work more efficiently and generate more power. It comes with an integrated velocity stack MAF housing, a black powdercoated airbox with a COBB badge, a pre - oiled cone filter, and is compatible with the stock tune and COBB '+SF' OTS Maps. Also, an installation guide is provided. Construction: The airbox is made of black powder coated aluminum. It has a slot in the front to take in air from the factory air scoop. Air is filtered through a larger pre - oiled filter and then directed to the velocity stack MAF housing. The wire - reinforced black silicone couplers are clamped at both ends for a leak - free install. Velocity Stack MAF Housing: This intake system uses special features to maintain optimal airflow and reduce turbulence. A custom conical air - filter element, a CFD - designed velocity stack, and a unique air flow straightener grid work together to smooth the incoming air for accurate readings. The one - piece high - temperature plastic composite design is lightweight and reduces heat transfer. Calibration: The SF Intake System is compatible with COBB Off The Shelf Maps. Look for '+SF' marked maps in your Accessport firmware.

Using the COBB SF Intake System is quite straightforward. First, refer to the installation guide provided to replace the factory intake and airbox with this intake system. Make sure all the clamps are tightened properly to ensure a leak - free install. When it comes to maintenance, regularly check the pre - oiled cone filter. If it gets dirty, clean and re - oil it according to the filter manufacturer's instructions. As for the airbox, you can simply wipe it down with a clean cloth to keep it looking good. Also, always use the COBB Off The Shelf Maps marked with '+SF' in your Accessport firmware for proper calibration. Remember, if you notice any unusual noises or a drop in performance, it might be a sign that something needs to be checked.
