This is the TPO BEAST Air intake kit, now available for Ducati motorcycles using the 4-valve engine. This kit replaces your factory velocity stacks with TPO's computer-designed stacks which flow more air, delivering MORE POWER.

 

You've asked us for these. We spent over a year developing them. Now you can unleash the BEAST on many Ducati motorcycles using the mighty 4-valve (and 3-valve) engines!

The TPO BEAST-4V Velocity Stacks are based on the same proven technology as our BEAST and BEAST-R intakes made for 2-valve engines. As with our popular 2V kits, the secret to the power gains of the BEAST-4V lies in our velocity stacks. The special shape of the velocity stack broadens the powerband peak and delivers additional horsepower and torque. Our proprietary design was created using computer airflow modeling and was perfected on the flowbench. This allowed us to fine-tune the length, angles, and radii of the stacks to deliver additional performance for both street and race applications. This special design offers the high-RPM flow of a short, race-style intake duct, while delivering a part-throttle power gain simultaneously. The TPO BEAST-4V is a no-compromise kit that delivers power gains throughout the entire RPM range of the engine.

 

The TPO BEAST-4V kit includes a pair of velocity stacks, sealing O-rings, and complete directions. This kit is a simple bolt-on installation. However TPO Parts recommends tuning in order to ensure optimum performance gains. The BEAST-4V works best when your Ducati is equipped with the proper air filters. We recommend the following filters:

  • Ducati Superbikes: OEM Ducati filters. (In our testing, aftermarket filters are either too small to properly fit the BEAST-4V stacks, or they resulted in a power loss)
  • Ducati Monster: K&N filter

These stacks will fit the Ducati Monster, ST3 and ST4 but they may not clear the factory air filter.

 


 

The BEAST-4V is not compatible with the 748R.
