Product Description

The Torque Solution TS-WH-497PA PNP Speed Density Kit with Aluminum Bung is designed for Subaru owners converting from a MAF setup to speed density engine management. The plug-and-play harness retains OEM-style connectors while adding a precision intake air temperature (IAT) sensor. The included aluminum weld-on bung mounts near the throttle body on the intercooler pipe for accurate air temperature readings, critical for tuned applications.

Perfect for performance enthusiasts and tuners running modified Subaru WRX and WRX STI models from 2002 to 2007 or turbocharged Forester XT and Legacy GT models from 2005 to 2012, this kit enhances tuning flexibility and throttle response. Professional installation and a custom tune are required to integrate the speed density system correctly.
