This new sealed induction system improves air flow and air density which increases the volume of air drawn into the cylinders.
The ECU then increases the fuel flow rate to maintain the air/fuel ratio which then produces greater combustion in the cylinders thus giving more power.
Each Dynatwist system is tailor made for individual models and offers all the benefits of a sealed induction system.
Cold air tubing is supplied with each kit and should be positioned down at the front of the engine bay so that as much cool air is channelled into the sealed chamber.
The top of the filter has a twist to it helping spin the air into a vortex for improved flow through the filter. The alloy shield protects the air inside from the heat of the engine so that as much cool air is delivered to the engine as possible.
Increases of 4-8bhp can be expected depending on vehicle and application. All kits are supplied with the necessary tubing and fitting materials.

That's what I may get.

Its sealed too, and a lot cheaper, maybe £140 ?
