Installation Notes
This valve control kit is designed for quick and clean installation using OEM-style connectors. The module and wiring must be installed in a dry, heat-protected area, and the harness must be routed professionally to ensure safe operation.
Installation should be carried out by a qualified specialist workshop.
Incorrect installation may lead to system malfunctions, performance issues, or permanent vehicle damage, and will void all warranty claims.
Safety Warning
Do not operate the vehicle at full throttle or high RPM with the exhaust valves permanently closed. This may result in excessive exhaust backpressure and potential engine damage.
