The Aeroflow Performance Mitsubishi fuel rail is specifically designed to suit Mitsubishi Evolution 4-9 models with the 4G63 engine. Proper fuel delivery is one of the most critical components for those looking to make all the power they can safely. The OEM fuel rails are incredibly restrictive and impede the fuel delivery to the injectors under high fuel pressures. Manufactured with a large internal bore, these fuel rails can support all necessary engine power requirements, especially with three -10ORB ports fitted along each fuel rail. Designedto suit 14mm fuel injectors and available in a variety of anodised finishes.
