HIgh performance aluminium velocity stack for airbox to throttle body union. This velocity stack replaces the standard part with an aluminium part that protrudes into the airbox. Through careful design it improves the engine response by providing an increased volume of less turbulent air to the throttle body. No modifications are required to fit this velocity stack but you should see a torque increase of around 6% at 2500 RPM and 3% increase in power at 6500 RPM

This manifold is suitable for EURO 4 and 5 models, manufactured on the shores of Lake Como. Developed for optimum power and torque on Mistral's rolling road. For best results combine with a performance air filter - SIA10433 and V-Twin Boost - ACA85001 or ACA85002.

Customer Kev fitted this combo and called us the next day to say that his V85TT was transformed; the fluffy throttle response between 2k and 3k was gone and the engine pulled better. Simple to fit, installation time is less than 30 minutes and the battery does not need to be disconnected.
