dsci Focus ST225 Induction Kit

 The Dreamscience dsci ST225 CAIS (Cold Air Induction System) is truly a revolutionary piece of kit designed to maximise the performance of your ST225 2.5L engine. The dsci kit is manufactured from top quality aviation grade aluminium and powder coated black. There is only one internal weld on this kit and for the most part a specialist mandrel bending machine has been used to form the turns and bends in the pipes. This kit also has rolled ends which offers better grip to the joining silicon hoses and boasts a venturi system which helps accelerate the air to the turbo inlet while providing a unique turbo note.

The dsci induction kit ticks all the boxes for a quality induction kit with a uniform pipe size throughout, no 90 degree bends, no expansion chamber like in some kits which can cause part throttle flat spots and hesitation, and no part of the kit is between the radiator and block so heat soak is not an issue. This kit was designed by engineers with PHD level qualifications in physics and is intended to maximise the performance of your engine and be the most efficient system for supply unrestriced cold air to the turbo with the shortest and most direct route.

As can be seen in the illustrations below Ford themselves have followed the same design with the RS MK2 induction as this is truly the most efficient way of supplying direct, cool air to the turbo.

The lower pipe has a K&N cone filter rated up to 430Bhp, we also offer a Piper cross equivalent for those who prefer a non oiled filter. The cone gets a direct cold air feed from the lower right grill and is still more than high enough to avoid any water contamination.

This kit is suitable for standard, partially and fully modified cars and in all cases will make a noticable difference to the overall performance and sound of the engine.
