2015-2021 Subaru WRX Stage 1+ SF Power Package by Cobb Tuning
The Stage 1+ SF Power Package includes an Accessport V3 and the Subaru SF Intake System!
The airbox is constructed of black powder-coated aluminum. A slot in the front of the airbox accepts air directed through the factory air scoop. Air is filtered through a larger pre-oiled filter and routed to the velocity stack MAF housing. The wire-reinforced black silicone couplers are sealed on either end with clamps for a leak-free installation.
This intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence. A custom conical air-filter element, CFD-designed velocity stack, and unique air flow straightener grid are designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The one-piece high-temperature plastic composite design saves weight and reduces heat transfer.
The COBB Stage 1+ SF Power Package is a simple bolt-on and tuning solution that will allow you to easily improve the power output of your 2015+ WRX! The heart of this package is the Accessport V3. It also provides increased airflow from the SF Intake & Airbox combo. Combine the airflow modifications and Accessport tuning upgrades for serious power output gains on your 2015+ WRX!

I purchased this intake and accessport back in September 2025 and the car drove amazing and had awesome sound especially in the autumn weather but after a few months I had frequent DAM drops as low as 0.312 using the OTS tune from Cobb. The car seemed all over the place in terms of smoothness in acceleration and proper boost. It would hesitate at times especially with bad gas and it felt sluggish. The engine didn’t seem too happy but still made a difference in power and sound overall. I eventually had the car e-tuned and that really made this mod worth every cent. I do advise getting an e-tune/Protune within a few months of installing if you don’t want to run into similar issues. To this day the car seems to perform in harmony thanks to the proper tune
When I first installed the access port and the intake I thought it would add just a little power but oh my was I wrong! It pulls so much better and longer! Sound of an intake is worth the money it self.
