The Tuyères and enlarged intake cones designed by us for the T-MAX 560 (2020/2023) are devices that improve air intake during the throttle opening phases. With their particular shape (Venturi-type cones), they reduce air turbulence during the intake phase, improve air intake from inside the airbox, facilitate intake, and reduce engine response time, especially during rapid throttle opening.Dyno testing has shown a gain of over 2.5cv (+8% power) compared to the original Yamaha tuyères. Installation without any modifications, plug-and-play. "Sport" air filter type DNA, SPRINT FILTER++. The tuyères and intake cones that we manufacture are shown in the test below, conducted on a DYNOJET power bench without ANY reprogramming. Enlarged T-Max Provence tuyères and intake cones. 2 enlarged intake tuyères + 2 Venturi-type cones + 4 stainless steel clamps. Manufactured by T-Max Provence, in our 100% workshop.
