X2R In-Line Performance Device (18300S-1)
The X2R In-Line Performance Device (18300S-1) is a smart, cost-effective performance upgrade designed to unlock the hidden potential of modern turbocharged engines. By optimizing boost pressure and fuel injection within factory-safe limits, the X2R can deliver up to 30% more horsepower and torque, resulting in stronger acceleration, smoother power delivery, and a noticeably more responsive driving experience.
Beyond performance, X2R’s advanced eco-tuning strategy helps improve efficiency during everyday driving. By refining torque delivery, encouraging earlier shift points, and reducing unnecessary high-RPM operation, drivers may see up to 20% improvement in fuel economy—without sacrificing performance when it’s needed. This makes the X2R ideal for daily-driven vehicles that demand both power and efficiency.
The X2R functions as an intelligent auxiliary control unit that continuously monitors key engine sensors such as boost pressure and intake air mass. It dynamically recalculates optimized values in real time and feeds them back to the ECU, enhancing performance while preserving all factory diagnostics, safety systems, and long-term reliability. Installation is quick and straightforward, typically taking 10–15 minutes with no special tools or mechanical expertise required.
