2015-2021 Subaru WRX and 2015-2020 Subaru WRX STI Accessport V3 by Cobb

Most drivers are content with only knowing how fast they are going, or how much gas is in the tank. If you are like us, though, all that just scratches the surface. There are no mysteries under the hood only questions that, when you can answer them, let you unlock your engine's full potential. Why leave horsepower on the table when the Cobb Accessport will allow you to unleash it with a quick, simple flash?

 

We'll show you how to boost the performance of your 2015-2020 Subaru WRX/STI with our Stage 1 MAPerformance Pro Tune. You'll enjoy gains over the stock setup specifically, 59 horsepower and 53 pounds of wheel torque at 93 octane using the Cobb Accessport V3.

The Cobb Tuning Accessport is one of our favorite ways to increase engine performance and monitor metrics in real-time. It's a fantastic-looking unit that mounts easily and offers bezels to match your interior.

While the Cobb Accessport looks amazing, it's also loaded with processing power, memory, and storage. Track up to six parameters at once, including your zero-to-60 time, shift lights, trouble codes, and more, directly from the ECU. Connect the Accessport V3 to your PC or Mac to manage maps, download data logs, and more.

Must have for any Subaru owner

Finally broke 36,000 miles so it was time to start modding my 2019 STi. Picked this up from MAPerformance for the additional STG1 Map. Flashed the Cobb STG1 HWG 91ACN map. Car accelerates smoothly now with no stuttering from garbage AZ gas. Also, throttle is no longer an on/off switch. Makes the car more driveable and fun. Must have item before any real modding can begin.
Shipping was quick, item was packaged safely.

Good product

East to install a little bit overpriced but you definitely need it if you are tunning your car. I felt a little bit more horsepower after and smoothness going through my gears as before with oem tune it was kind of jumpy in the beginning and in the higher rpm’s car just pooped out.
