Power Without Worry!

There's no secret to getting additional power from a turbo engine - turn up the boost! But it's easy to take things too far and become "boost drunk". If what you're after is a generous bump in power without worrying about reliability, compromises, or additional modifications the aFe Power Scorcher is perfect for you. We've tried the Scorcher in a number of different BMWs and can report back that it works flawlessly!

Our findings:


  • Incredibly simple installation - by the third car we tested with we had the install down to 5 minutes!
  • High build quality - it looks and feels like a real part - not homemade like others we have seen
  • Immediate power gains - right from our parking lot we could feel the substantial difference
  • Affordable power - great bang for the buck

The Scorcher is a plug-and-play tuning module that installs on the engine wiring harness and modifies the signals from the manifold pressure sensors. The new signals are then sent to the engine computer which increases boost based on the modified signal. The power gains are instantly noticeable and the module has been fully engineered to deliver a smooth and reliable power boost over all RPM. aFe developed this module upgrade on their in-house Mustang and Dynojet dynos as well as using them on their own BMW 328s. There are other products that give more power (for additional cost) but more boost also brings more complications. This is all of the power you need without additional drama and trickery. The Scorcher can be used on its own or combined with other aFe Power products for the total package.

The install is very easy with no cutting or modification to existing components. Unplug the harness from your MAP sensors and plug it into the Scorcher module. Then plug the Scorcher harness into the MAP sensors. Mount the module wherever you wish (Velcro and zip ties included). A blue LED lets you know the module is plugged in correctly and functioning. You can also revert back to stock just as easily! The Scorcher is built with a 0.1% tolerance on critical components. Each connector is an OE type for the best and most secure fitment and they use high quality wiring with excellent heat and chemical resistance. The module box is aluminum with a hardcoat anodize finish. This is way beyond the other 'resistor in a box' products on the market. aFe warranties the complete unit for two years.
