MCS Manifolds

4 products — part of all Manifolds

Intake manifolds are the junction between the air cleaner assembly and the cylinder heads on your Harley-Davidson, and a worn, cracked, or incorrect manifold degrades both performance and fuel efficiency before the engine shows any other signs of wear. MCS supplies replacement intake manifolds across a wide range of Harley-Davidson model applications, covering carbureted Evolution and Sportster engines as well as EFI-era Big Twins where throttle body spacers and manifold adapters form part of the intake path. Selecting the correct manifold for the application ensures the air cleaner and carburettor or throttle body seat without air leaks — a leak at the manifold causes lean running conditions that are difficult to diagnose without knowing the manifold is the source. Iron City Motorcycles in Leeds stocks MCS intake components alongside carburettor kits, air cleaners, and the hardware needed to complete an intake system rebuild on a Harley-Davidson.
