The FMINDK38 is theย cold air induction system for Fordโs latest generation 1.5-liter 3-cylinder ST engine. Like with allย manufacturersย in recent times the need to make smaller engines more efficient and more powerful has been an engineerโs top priority, this then creates a problem for the aftermarket manufacturers to improve what is already fitted to the vehicle, nevertheless this hasnโt stopped us at Forge Motorsport.ย On a tuned vehicle this combination is an essential purchase as the OEM air box is found to be too restrictive to achieve the optimum power figures and smooth power delivery.

This beautifully crafted high flow charge pipe is for theย Ford Fiesta ST MK8ย andย Ford Puma ST. This product has been created over many days and months of dyno testing and road testing to prove the products credentials. The boost pipes areย aย direct replacementย to the original hot-side charge pipe which is rather restrictive especially at the turbo end. FMBP6 was developed to remove these restrictions and now features aย smooth and enlarged bore sizeย creating a vast improvement in air flow and a reduction in pressure drop.
