aFe Scorcher Module 16-17 BMW 340i/xi 9B58)

aFe's Scorcher module adds power to the B58 by adjusting the pressure sensor signals the engine computer sees, which lets the turbo make more boost. It plugs into the factory wiring at the sensor connectors, and aFe says it leaves no trace on the ECU. A small LED switch, which you can mount anywhere in the cabin, chooses between four power levels.

What you get

• Plug-and-play module that connects to the stock harness and sensors.
• Four power settings chosen with an in-cabin LED switch.
• No permanent changes to the ECU, per aFe.

Good to know

• aFe advises against running it together with other tuning devices or modules.
