Overview

The Stratified Automotive Controls X4tra Fuel System is an auxiliary fuel system designed for EcoBoost 2.0T and 2.3T powered vehicles. It addresses shortcomings in the high-pressure fuel pump (HPFP) and injectors. This system provides precise and increased fuel delivery to each cylinder.
Show original supplier description
The Stratified X4tra 4-Port Fuel System is a plug-and-play auxiliary fueling solution engineered to tackle the HPFP and injector limitations in EcoBoost 2.0T and 2.3T engines. It builds upon the capabilities of the Stratified Xtra 2-Port system by delivering more precise and enhanced fuel delivery to each cylinder, making it a highly recommended upgrade for those aiming for 500+ WHP with an upgraded turbocharger. This system features injectors angled towards the cylinder head, utilizing a split stream pattern to ensure even fuel distribution to each intake valve. This design not only promotes proper air-fuel mixing but also ensures each valve receives consistent fuel cleaning. The ports on the spacer are angle-matched to fit between the intake manifold and cylinder head, maintaining a smooth airflow transition into the engine and preventing power loss from abrupt transitions common in straight-port intake spacers. The X4tra system supports E85 blended fuel and full E85, though an OEM LPFP upgrade is recommended past 400 WHP when running full E85. It is capable of supporting over 650 WHP, with the option to upgrade to larger injectors for even greater power potential. It's important to note that the 2.3 flange option for the turbo manifold will absolutely not fit a 2.0 cylinder head and is intended for users upgrading the turbo while performing a motor swap simultaneously. This product is intended for race or off-road use only.
