REVO Ford Fiesta ST – OEM + AIR INTAKE SYSTEM
-Revo Hi Flow Panel Filter
-Custom 70mm Mandrel Bent Pipe
The Revo OEM+ Air Intake System for the Ford Fiesta ST is a high performance upgrade that utilises the stock air box, offering gains in both power and torque.
Initial flow testing of the OEM system highlighted the restriction and turbulence caused by the pipe joining the turbo to the airbox. The route varies in diameter and convolutions in the pipe slow airflow to the turbo, choking the engine. The OEM airbox performed far better than expected when used in conjunction with the Revo enhancements.
The Revo system is the only kit currently available that replaces the rear plastic back-pipe with a one-piece 70mm aluminium pipe. Automotive grade silicone couplers connect the system to the stock airbox and a Revo 3 stage foam panel filter replaces the restrictive paper filter. The Revo OEM+ Air Intake system was found to be less restrictive than the stock system during testing and continued to flow air long after the stock system maxes out.
