Sprint Filter, the world's oldest manufacturer of performance air filters since 1952, as well as current leading supplier of World Motorsport and Romeo Ferraris, the Alfa Romeo Giulietta TCR racing machines builder, will cooperate for the 2019 racing season in the WTCR and all 2019 TCR National Championships. Romeo Ferraris has tested on dyno the Sprint Filter KD1TCR intake and has decided to homologate this intake kit totally manufactured in carbon fiber with autoclave process where is fitted inside the patented Sprint Filter P037 waterproof air filter for dusty conditions or the Sprint Filter P08F1-85 patented waterproof air filter to gain the max performances. Test and dynamical tests carried out by Romeo Ferraris technicians have demonstrated the incredible efficiency of the Sprint Filter P037 and P08F1-85 air filters with a sensible performance improvement, especially in the dispensing area starting from the maximum torque to the maximum engine speed, just when it increases the "requirement" of engine air.
