The Torque Solution Plug and Play (PNP) Speed Density Adapter Harness provides a seamless solution for transitioning your Subaru from a factory Mass Air Flow (MAF) based setup to a Speed Density tuning configuration. This adapter eliminates the need for cutting, splicing, or pinning the factory engine loom, ensuring a reliable electrical connection while preserving the integrity of your original wiring harness.

Built with high-quality wiring and OEM-style connectors, this harness is designed to withstand the heat and vibration of the engine bay. It is a critical component for high-performance builds where the factory MAF sensor becomes a bottleneck or when custom intake piping requires the relocation of intake air temperature (IAT) and manifold absolute pressure (MAP) signals.

  • Enables Speed Density conversion without permanent harness modifications
  • True plug-and-play installation for a clean, professional finish
  • High-quality, weather-sealed connectors for long-term reliability
  • Retains factory wiring integrity for easy reversal to stock
  • Manufacturer Part Number: TS-WH-499
