N1 Clutch Master and Slave Cylinder Upgrade Kit

The SiriMoto N1 Clutch Master CMC / Slave Cylinder Upgrade Kit is designed to enhance the clutch system in manual transmission Honda Civics, specifically for the 9th generation models (2012-2015). The problematic factory Clutch Master Cylinders (CMCs) on many newer Hondas and Acuras feature a dampening diaphragm to reduce pedal vibrations, but this component is prone to leaking or failure, which can leave the driver stranded. Similarly, the factory Clutch Slave Cylinders often include a delay valve that limits engagement speed, hindering performance driving and potentially increasing clutch wear. SiriMoto's N1 kit addresses these issues by eliminating the dampening diaphragm in the CMC and the delay valve in the slave cylinder. This upgrade provides drivers with better control over clutch engagement, removes potential points of failure, and creates a more robust system capable of handling performance clutch kits. The result is a more engaging and fun driving experience. The kit is a direct bolt-in installation and includes all necessary components: the N1 Clutch Master Cylinder, N1 Clutch Slave Cylinder, N1 Hydraulic Clutch Line, and installation hardware. The clutch line features stainless steel braid construction with a PTFE inner coating and a black PVC outer coating for durability and resistance to fluids. Developed for track performance, the SiriMoto N1 kit utilizes modified Exedy clutch cylinders, known for their OEM quality. These are then customized with premium alloy and stainless steel components to ensure a direct bolt-on fit. Installation instructions are available upon request, and gravity bleeding is recommended as a first step, followed by using the provided bleeder screw for pressure bleeding. For some applications, the OEM clutch master cylinder clevis may need to be reused.
