If uncompromised performance is the custom approach you seek, the British Customs Billet Intake Manifolds have been designed to deliver it in droves.

Machined from billet aluminum, our vortex design offers less air resistance, boosting performance by increasing airflow for better fuel atomization. You’ll feel improved low-end torque, throttle response and acceleration right from the hop. With heavy-duty rubber flanges and machined O-ring grooves, our intake mani-fold seals better than stock and is less prone to air leaks. We’ve even engineered them to provide extra support for larger carburetors and for stock units running without the factory air box.

Finished in anodized black, the BC Billet Intake Manifolds accent your bike and stand up to weather, fuel and abuse.

NOTE: This custom part is not compatible with the stock air box. Air box removal required – British Customs Air Box Elimination Kit recommended.
