This High Flow exhaust manifold from 034 Motorsport for 1.8T longitudinal engines is designed to improve performance without requiring any modifications to the engine compartment.
Thanks to 50% larger runners and an optimised design, airflow is significantly improved. This results in increased power and faster turbo Spool-up, whilst maintaining compatibility with OEM turbos and downpipes. Ideal for upgrades such as K04-001 and GT “Eliminator” setups.
