Description
The (TUR) FORD BARRA I6, produced between 2002 and 2008, became one of Australia’s most iconic performance sedans and utes. Central to its success was the Barra I6 engine, a 4.0-litre inline-six turbocharged petrol unit with DOHC (Double Overhead Camshaft) configuration and 24 valves. However, the PG260 inlet system was designed with compatibility across a wide range of engines, including Ford’s Barra I6 and Duratec I4, Holden’s RB30ET, and Nissan’s RB20DET, RB25DET, VG20ET, and VG30T engines. Another key point, this versatility highlights the importance of inlet systems in turbocharged performance vehicles, ensuring efficient airflow and maximizing combustion.
