The Stage 1 Power Package Includes the Accessport and High Flow Filter for the 2025 + Toyota 4Runner.
The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Toyota. 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.
This version of the Accessport includes the capability to flash the TCM which is the unit that controls the transmission. It includes various Off The Shelf transmission tunes which adjust shift points, shift firmness, skip shift behavior, and torque limits to fit your preferred driving style.
This Accessport includes a Gateway Bypass Harness. To use it, connect the harness to your vehicle’s OBD-II port, the Gateway connector, and then to the Accessport. The Gateway Bypass Harness enables ECU communication in situations where the Accessport would otherwise be ignored—such as during initial installation, when dumping an unsupported vehicle ROM file, or when recovering from a failed flash. It is not required for map changes or uninstalling the Accessport.
COBB High Flow Filters are designed to permit very high flow rates, minimize restriction, maximize filtration and provide a long life filter. Using propriety Woven cotton and metal mesh with a precision molded rubber base, the COBB High Flow Filter ensures that only clean air passes into your engine for maximum efficiency. Why not treat your car to fresh air with a COBB High Flow Filter and let it reward you with increased power, fuel economy and money savings!
Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.

Why?
The in-cabin mountable Accessport V3 has a large, full color, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. This is your new Accessport - and maybe the last one you'll ever need.
