TPO BEAST Air Intake Kit
Applications:
- 2002-2008 Fuel injected monsters. Does not fit the 4-valve models, or the 696
NOW AVAILABLE:
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 and matched K&N Air filters. 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!
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.
We combined our special BEAST stacks with a matched set of K&N Air filters. These air filters have nearly twice the surface area of the OEM filter. This provides a much lower pressure drop across the filter, feeding your engine all the air it needs without restriction.
TPO BEAST Air Intake, with its special velocity stacks and matched K&N conical filters, can flow 18% more air than the stock intake with NO FILTER and NO AIRBOX LID at all! This translates into power gains across the board: The BEAST kit provides more horsepower from off-idle all the way through Redline!

Our K&N filters have a one million mile warranty, and never need to be replaced! Just clean them according to the included instructions every 30,000 miles. Installing this kit is not weather-sensitive; you can ride in the rain or park your bike outside with no ill effects.
The BEAST Air Intake comes in a complete, ready-to-install kit. With some basic tools, you will be ready to unleash the BEAST in less than an hour. This kit includes:
- Step-by-step directions with color photos
- One pair of velocity stacks
- One pair of genuine, pre-oiled, K&N air filters
- Precision-cut bracket
- Stainless Steel hardware
- 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.
