2019 Subaru WRX STI Support

Subaru’s newest WRX STI is now completely supported within the COBB ecosystem.  The Accessport, bolt-on upgrades, Stage Power Packages, and Off The Shelf Maps make upgrading your STI a straightforward process.  Interested in taking your STI beyond the scope of our packages and maps, contact one of our Subaru Protuners for a completely customized tune!

Visit the 2019 Subaru WRX STI Vehicle Page for a full list of compatible parts.

Accessport
accessport_v3_subaru The Accessport is the world’s best selling, most flexible, and easiest to use ECU upgrade solution for your Subaru. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It’s the last engine management solution you’ll ever need.

New SF Airbox and Intake Airbox Combo

The addition of a new Intake Airbox Combo is the main difference in our bolt-on part offering for both the 2018 STI Type RA and 2019 STI.  Subaru’s updated factory air duct that directs air from behind the grill into the airbox is not compatible with the COBB SF Airbox.  To address this, a combo specific to these vehicles has been created.  This combo includes the Subaru factory intake duct from the 2015-2018 STI, allowing for a true bolt-on application.

Off The Shelf Maps

We offer a number of Off The Shelf Maps to accompany almost all of the available Stage Power Packages for your 2019 Subaru WRX STI.  Below are dyno charts to show power gains realized at each Stage with Stage1 providing a nice bump in power and torque over stock and Stage3 maximizing the efficiency of the factory turbocharger on pump fuel.  Each of these maps will come pre-loaded onto the Accessport and is also available as a download from the Maps Section of our website.

Please visit the Map Notes Page for a complete understanding of mechanical requirements for each Off The Shelf Map.

2018 Subaru WRX STI Type RA

The same updated Intake Airbox Combo for the 2019 STI is the key to upgrading your 2018 STI Type RA beyond the Stage 1 level.  With the addition of the new combo, we are also now able to provide a complete offering of Stage Power Packages and Off The Shelf maps for your 2018 STI Type RA!

New Off The Shelf Maps

Upon release, and for the past few months, the only COBB Off The Shelf Map available for the 2018 STI Type RA was a Stage 1 calibration for either 91 or 93 octane fuel.  Today, we are excited to announce a complete list of maps for the RA.  With the addition of new hard parts and further testing on-car, COBB is now offering Stage1+, Stage2, and Stage3 Power Packages with accompanying Off The Shelf Maps!

2019 Subaru WRX CVT Support

Lastly, Accessport tuning support for the 2019 WRX CVT is also now available.  As the vehicle remains largely unchanged from previous years, compatible parts and available map files remain the same. The Stage 1 and Stage 1+BigSF Off The Shelf maps are included in Accessport firmware and provide gains within the tolerance of the CVT transmission.
