2015-2021 Subaru WRX 6MT NexGen Power Packages and Maps

With this release we are extremely excited to announce the first of our revised “NexGen” Power Packages and accompanying Off The Shelf Maps for the Subaru platform, NexGen Stage 2 Power Packages for the USDM 2015-2021 Subaru WRX 6MT. In our never ending strive to provide additional upgrade options for owners of these vehicles, the Subaru Experts here at COBB took to our dyno to define our emissions compliant, NexGen Stage 2 Power Package utilizing products from our catalog that have an existing CARB Executive Order (EO) or have a known path towards obtaining one. What came as a result of extensive testing on the dyno, street, and even several trips to our local track are NexGen Power Packages which provide impressive power gains over the existing Stage 1 level.

While these NexGen Power Packages and OTS Maps are currently emissions compliant and available in 49 states, we expect a CARB EO for them very soon. At this time, Stage 2 NexGen OTS Maps are ONLY available to download off our website. Once we receive a CARB EO, they will be added to Firmware on the Accessport (AP3-SUB-004).

As we have previously mentioned, there is NO emissions compliant aftermarket / upgraded J-Pipe for the FA20DIT WRX. While this misinformation is abundant, we’re working on a compliant solution and Executive Order path for J-Pipes on these vehicles. Until then, the J-Pipe is no longer a feasible component of our recommended upgrade path or power packages.

Power Gains

The question you’re likely all curious about is how much power this combination is capable of while retaining the factory j-pipe and cat configuration. We’re happy to say that this package and OTS combination does provide meaningful power gains over existing Stage 1 and Stage 1+Intake. Most importantly, this power increase is both reliable and repeatable with the increased cooling efficiency of the COBB Top Mount Intercooler. Boost control is also more precise and consistent with the addition of the COBB 3-Port EBCS.

These packages are offered in four different flavors but contain the same core components and are capable of achieving the same power levels. Each kit includes an Accessport (SUB-004), Intake (either Big SF or Redline), Top Mount Intercooler (Black or Silver), Charge Pipe, and Electronic Boost Control Solenoid.
