As you may already know, the stock fuel system on the FK8 and FL5 Civic Type R and DE5 Integra Type S is the primary bottleneck in making more power. Now, with the Civic FK8 FL5 / Integra DE5 Fuel System Upgrade, you can finally take your Honda Civic to a new level of power! This fuel system upgrade consists of a unique set of fueling related hardware components that allow nearly 25% more fuel flow (and almost 50% with the Fuel System Plus option) compared to the stock fuel system. This system is very reliable and engineered to the highest possible specifications for durability and performance!

Key Features:

• Allows your FK8 or FL5 Civic Type R or DE5 Integra Type S to exceed the power levels of the performance inhibiting factory fuel system.
• Plug and Play (PnP) upgrade - bolts right on to your other stock fuel system components and can easily be uninstalled if needed. Nothing is cut!
• Ideal for use with an E85 Flex Fuel system, but also delivers great gains with pump gas. All components have been E85 ethanol tested.
• Tested on multiple cars for over a full year.
• With stock turbo and engine, Hondata was able to run full E85 without any fuel pump limitations! The stock engine torque increased 41% from 333 to 468 lb-ft and power increased 35% from 317 to 428 hp. With a turbo upgrade, Hondata has tested to over 500 hp - an amazing 60% power increase over stock. Supporting bolt-on performance parts are required for getting the best power gains. More power is possible with the Fuel System Plus option!
• Nearly 25% more fuel flow than the stock fuel system. The Fuel System Plus option provides almost 50% more than stock.
• Upgraded clutch recommended. Engine internal upgrades recommended when using the Fuel System Plus option.

Kit Contents:

• High flow low pressure fuel line.
• High flow direct injection high pressure fuel pump.
• High flow high pressure fuel line.
• High flow DI (Direct Injection) fuel injectors. The Fuel System Plus option features special 1530cc Hondata DI fuel injectors that provide even more flow.
• Fuel System Plus option includes a special exhaust camshaft (for delivery of even more fuel volume without loss of pressure).
• Optional high flow in-tank low pressure fuel pump kit. This pump is usually needed if you're making more than 500 hp with flex fuel or 550 hp with high octane race fuel. However, if your DIFP (direct injection fuel pressure) is dropping, you need this low pressure fuel pump upgrade.
• Precision Hondata FlashPro software control. Multiple free calibrations starting with an increase of 92 lb-ft torque and 59 hp over stock.

Component Notes: All the above components are E85 ethanol tested and are necessary for proper functioning of this system. You cannot piece together components or just buy a few of them. They have all been designed to work together.
