BMW E39 540i Turner IAT Relocation Harness
Introducing the Turner IAT Relocation Harness. BMW designed your air intake system in a way that put the intake air temperature sensor close to the engine, subjecting your engine's computer to air temps that are artificially high. When the ECU reads these warmer temperatures, timing and fueling are cut, resulting in less power and torque.
By relocating the IAT to a less heat soak prone position within the air intake tract, the Turner Motorsport relocation harness offers a safe, power-preserving, plug-and-play solution to heat soak - for better, more consistent power delivery.
Stop taking the heat.
