With this upgrade you get all the fittings needed to upgrade your kit to the benefits of direct injection. This includes the manifold, 1/8" NPT fittings, and a small portion of tubing to hook it all up.

Direct Port Setup: Why would you want to install a direct port setup? Because injecting equal amounts of water methanol into each cylinder is critical. Also, it could be because you need to distribute the methanol through multiple spots in the motor to achieve better droplet size and better distribution.
Installation: You will want to install the this manifold upgrade after the check valve or solenoid. We usually recommend putting each nozzle as close to the cylinder head as possible and because you are injecting post throttle body and the vacuum in the inlet then the check valve will need to be upgraded/replaced with a solenoid.
Application: Direct port injection is normally done with 4, 6, or 8 ports
