Roller Barrel Upgrade Set, 3 Stud Manifold, 3.6L
This Rennen by JSR upgrade set brings roller barrel individual throttle bodies to a Porsche 964 3.6 litre engine with a 3 stud inlet manifold, finished in gunmetal with silver velocity stacks and classic mesh air filters for a timeless Porsche look.
Each cylinder gets its own dedicated throttle body in place of a single butterfly plate, so airflow is less restricted and throttle response is far more direct. Fuel rails are machined for EV6 injectors and a precision mechanical linkage keeps the driving feel analogue.
