For custom applications, this is a set of BEAST Air Intake Velocity Stacks. This product includes the Stacks only, and is perfect for experienced builders who do not require the coil bracket, filters, hardware, or directions. Integrate TPO technology into your next project with the best air intake solution on the market.


The TPO BEAST is the original high-performance intake kit for your Ducati Monster. The TPO BEAST intake features custom-designed billet aluminum velocity stacks. Installing this kit on your bike RAISES HORSEPOWER and SAVES WEIGHT at the same time.

The TPO BEAST Air Intake System is totally unlike any other air filter product or modification out there. This kit replaces the restrictive stock airbox assembly with our specially designed BEAST velocity stacks. Not only does this make your bike significantly lighter, but it also offers the maximum possible airflow-giving you more power.

  • BETTER than the stock filter
  • BETTER than "open airboxes"
  • BETTER than a K&N, BMC, TwinAir, or any other "performance" flat filter
  • BETTER than foam filters
  • BETTER than NO FILTER!
How is this possible?

The secret to the performance gains of the BEAST kit lies in the velocity stacks. These are billet aluminum "funnels" which guide intake air into the throttle body of your engine. We designed the BEAST velocity stacks using sophisticated computerized airflow modeling software which runs on a supercomputer (COSMOS and Abaqus). Our computer-optimized design was then tested and fine-tuned on a flowbench and again on a dyno. The result is that the special shape of our stacks increases horsepower over the entire RPM range of the engine.

  • Four pounds of weigh saved
  • Up to 10 HP increase
  • Increased HP and torque throughout the entire RPM range
  • Awesome sound when you hit the throttle

The BEAST Air Intake System is for 2002-2008 Fuel injected monsters, EXCEPT the 4-valve models (S4, S4R, and S4RS). It works on all other Monster variants including "Dark", "S", "Metallic", "IE", "S2", "S2R", etc. While it is possible to install this kit on your bike without tuning, TPO recommends that you take your bike to your dealer and have them tune your ECU to maximize the performance gains of this kit. Tuning is optional, but suggested because it will maximize the HP gains of the kit. Tuning requires an exhaust gas analyzer and should take less than fifteen minutes using adjustments that are built into your bike's ECU from the factory. You do NOT have to buy "chips", "Power Commanders" or other expensive tuning devices.

The exact HP gain from the BEAST Kit will depend on your engine size as well as what other modifications you have on your motorcycle.

NOTE: There are significant differences in the dynamic power gains between the basic and Type -R BEAST Kit. Please read this FAQ here to find out more about this.
