Cobb Stage 1 Power Package 2025 Toyota 4RUNNER

Unlock the full potential of your 4Runner with the COBB Power Package. This complete performance upgrade combines the industry-leading Accessport ECU tuning solution with the COBB High Flow Air Filter to deliver noticeable gains in power, response, and efficiency—without sacrificing reliability or drivability.

Accessport V3 – Ultimate Engine and Transmission Control
The COBB Accessport is the world’s most popular and versatile ECU upgrade solution. It replaces factory-conservative calibrations with performance-optimized tuning to unleash hidden power from your engine. Pre-loaded Off The Shelf (OTS) maps provide instant improvements, while the option for custom tuning supports any modification level.

This version of the Accessport also enables Transmission Control Module (TCM) flashing, allowing you to fine-tune shift points, firmness, skip-shift behavior, and torque limits for a truly personalized driving experience.

Included with this kit is the Gateway Bypass Harness, which ensures proper ECU communication during installation, ROM extraction, or recovery operations. It’s not required for standard map updates or uninstalling the Accessport.
