2021-2026 Ducati Multistrada V4 / Diavel V4 (ALL 1158cc Models) Velocity Stack Kit

With the success and positive feedback we've gotten from our Ducati tuning, we wanted to turn our focus to getting air into the engine in a more efficient way. Perfection takes years and we didn't bring this to market until we finally found a way to make a velocity stack we were proud to put our name on. We are the only company producing working and readily available velocity stacks for this platform! Our custom velocity stacks not only give a very decent top-end power increase but also a midrange bump, making it a no-brainer modification. OEM-level quality, straightforward install, these custom velocity stacks mimic what Ducati race engines have been trying to provide in sanctioned racing, but for your manufacturer spec motor. We managed to make more power where it matters without sacrificing that torquey punch that many really enjoy in the Multistrada V4. We were able to create low, mid and high horsepower gains which is usually unheard of with an airbox change.

Experimenting with designs and studying all variations of the V4 motor and how the airflow model operated, we finally found a design that adds power with no downsides. We spent months testing and developing this exact design. With our race induction kit, you will get the parts and tuning needed to maximize your Multistrada V4. The more airflow (air filter / exhaust) and the better the octane used, the larger the gains. This product accomplishes all the goals we were aiming to hit.

WHY THIS IS A MUST HAVE MODIFICATION

Huge gains with a cost effective and easy to install modification. Our proven and tested Race Induction Velocity Stack Kit is good for 10HP over stock and brings you beyond the Multistrada RS power levels while still having a HUGE torque increase everywhere else. This is a must have modification for your Multistrada V4. In the graph below you can see the huge gains in the high RPM which makes a massive difference on the 1158cc engine.
