Roller Barrel Upgrade Set, 2 Stud Manifold
Built for a modified Porsche 911 3.0 litre engine with 41mm inlet ports, this Rennen by JSR upgrade set pairs gunmetal throttle bodies with silver velocity stacks and classic mesh air filters for a period-correct motorsport look.
Each cylinder gets its own dedicated throttle body, so the engine responds instantly and breathes more freely through the rev range. A precision mechanical throttle linkage keeps the driving feel direct and analogue.
