Cobb Tuning

The best Cobb Tuning upgrades start with the AccessPORT V3 handheld tuner, which unlocks performance maps and live engine monitoring for supported models like the 22-26 WRX and 15-21 WRX/STI. Beyond tuning, Cobb's bolt-on catalog — high-flow filters, shifter stops, intake parts, and drivetrain upgrades — sharpens the driving feel of your daily driver. If you own a supported Subaru, Cobb is one of the most complete aftermarket ecosystems you can buy into.

Cobb built its name on engine management: the AccessPORT connects to your OBD-II port to reflash the ECU with off-the-shelf or custom maps, while doubling as a digital gauge display. Around that core, Cobb offers supporting hardware designed to work together as staged upgrade packages, so pairing the tuner with Cobb's own bolt-ons keeps everything compatible.

Match the exact part number to your year and model: AccessPORTs are year-range specific, with separate versions for 22-26 WRX and 15-21 WRX/STI. Some parts span multiple chassis, like the shifter stop listed for 15-26 WRX manual models, while others cover additional vehicles such as the Ascent and Legacy XT. Always confirm fitment on the product page — check your year and model.

FAQ

Is the Cobb AccessPORT compatible with my car?

AccessPORTs are model- and year-specific — a tuner for the 15-21 WRX/STI will not work on a 22-26 WRX. Check the fitment line on the product page for your exact year and model.

Does installing Cobb parts require a tune?

The AccessPORT is the tune itself, but intake and exhaust hardware generally needs matching map support to run safely. Bolt-ons like the shifter stop need no tuning at all.

Can the AccessPORT monitor my engine?

Yes — beyond flashing maps, it works as a live gauge display for boost, temperatures, knock, and other parameters.

Will Cobb parts void my warranty?

An ECU reflash can affect powertrain warranty coverage, so check with your dealer before tuning. Cosmetic and interior accessories carry no such concern.
