Honda Civic X L15B7 Port Injection Fuel Rail Kit by MAPerformance

When it comes to increasing the power output of a vehicle, most people imagine building their engines or bolting on a larger turbo, but the unsung hero of reliable power delivery is often the last, and arguably the most critical component of the power delivery system, namely, the fueling.

Many modern vehicles utilize a form of fuel delivery known as direct injection. The direct injection uses the in-tank fuel pump to supply a mechanical fuel pump that increases the fuel pressure to a very high level before feeding the injectors. This type of system typically benefits more from fuel pump upgrades rather than injectors as the injectors are, for the most part, capable of introducing as much fuel as high-pressure fuel pump can provide. Once you find the limit of your high-pressure fuel pump, there were no viable methods to increase fuel delivery to the engine...until now.

The MAPerformance Port Injection Upgrade kit provides you with a direct bolt-on option for your Civic X 1.5T, allowing you to add the supplementary fuel needed to take safely make the power that today's bolt-on turbos and turbo kits are capable of making! When designing this kit, we had a few key tasks we wanted to accomplish, starting with a product that had a very simple install and could be done with standard hand tools, next on the list was optimizing the injector angles to provide the best spray pattern into the intake tract allowing the fuel to disperse in the most uniform possible way. With those in mind, we designed our bolt-on spacer, and the custom fuel rail to do exactly that! This kit does not replace the factory Direct Injection system, rather it adds additional capacity to the system.

The kit was designed to utilize two different height injectors, the 48mm, and the 60mm, both utilizing a 14mm upper and lower O-ring. Some options are listed below, but there are more available. Additional plumbing will need to be done to get fuel to the rail, please consult us with any questions on the needs of the kit! This adapter is designed for a DIY plumbing kit and therefore will come with no lines or plumbing. We do have a kit in the works, but for now, the DIY customers at least have an option!

PLEASE NOTE: FUEL INJECTORS ARE NOT INCLUDED IN THE KIT, AND WILL NEED TO BE PURCHASED ADDITIONALLY
