The Thumper Ported intake manifold for the R50, R52, R53, R56 one, cooper and cooper S bmw mini gets rid of the restrictive bottle neck effect that the standard Intake manifold causes once the Cylinder head has been ported.

By porting the Intake manifold as well as the cylinder head this then allows them to marry up and match each other allowing the maximum gas flow through out.

Porting the intake manifold has seen increases in both horse power and torque simply from smoothing the transition form the intake manifold to the cylinder head. We strongly recommend porting the intake to ensure the most out of your Thumper head.

Please Note: We require your old Intake manifold in exchange All manifolds will need to be sent direct to Thumper. We will provide the address once you have receipt of your intake manifold. Once Thumper have received your manifold we will refund you £100.00 from the price shown. If you do not wish to send your manifold no refund can be given.
