Maintaining fuel pressure is the difference between blowing a motor and not. When fuel pressure drops, air fuel ratio goes lean.
XDI gives us the difference we have been searching for.
If you any of these are on your mind, then you need an upgraded high pressure fuel pump.
This GDI high pressure pump was developed to replace the Denso OEM high pressure pump. It delivers up to 45% more fuel flow when mounted on the same CAM-Lobe. Maximum Fuel Pressure is 200bar / 2900psi with the XDI-A007-27, while 250bar / 3625psi with the XDI-B007-27. The kit comes with everything you need: the HPFP, base plate, hardware and an electric pigtail. It is a true bolt on solution, factory inlet and High Pressure line fit. The swap can be done in your garage without any special tools.
