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. Quick rush to market velocity stacks with no REAL data have been available and from them we learned shorter is not always better. 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 is widely considered the hallmark of the 1103cc V4 engine. 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. We even tested all of our competitors to see where they fell short and how we could improve. We have found our design makes the best power for the 1103cc, 18-24 V4 engine and the revised 25 V4 engine. With our velocity stack kit, you can run factory tuning, UpMap / Akra tuning, or use our tuning that is specifically catered to this design, and with fantastic results. 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.
