FORGE induction kit for Ford Fiesta ST Mk8

Description

The FORGE induction kit replaces the standard airbox. Development included weeks of real-world testing and hours on the dyno with different filters. The FORGE pleated filter gave more power and torque while filtering very well. The filter media is a high-flow synthetic nanofiber, pleated for a larger surface area and higher flow. A silicone coupling and W2 stainless steel hose clamps join the filter to an anodised black machined billet velocity stack. The velocity stack is the MAF sensor housing and smooths airflow into the sensor and inlet tract.

Together, the filter and MAF sensor housing gained 4 bhp on the dyno. Torque rose from 1500 to 3000 rpm and from 4500 rpm to the red line, with 20 Nm more at 2200 rpm. Induction sound is louder under hard acceleration, and turbo flutter can be heard when lifting off the throttle. A laser-cut, powder-coated aluminium shield surrounds the filter. It protects the filter from engine heat and uses the OEM air ducting to bring in cold air. The kit causes no engine management light.

Installation

The kit fits the original inlet hose and inlet hoses from other manufacturers. It can also be paired with the FORGE silicone intake hose, which further smooths airflow to the turbo.
