Tdi Twin Inlet Tuned Manifold.

These manifolds are individually tuned on a flow bench to maximise and balance the flow of air to the inlet ports on the cylinder head.

Each manifold is fine tuned to give a balanced air flow across all ports 


When you supply each cylinder with the same precise dose of air, at the same pressure, then you harmonise the torque given to the crankshaft for every power stroke.


Price is for a drop in full kit, the balanced manifold, the two elbows, the collector pipe and pipe clips

Price is based on exchange. A refund of £50 will be given on exchange of an existing Tdi 200 or 300 manifold, returned within 30 days of purchase.
