Product Overview
The Exoracing Silicone Hose Kit Honda Civic FN2 K20Z4 is a 14-piece black silicone hose set designed specifically for the Honda Civic FN2 Type R with the K20Z4 engine. This kit (manufacturer part number EX-SILI-K20Z4) upgrades the original rubber coolant and vacuum hoses to high-grade silicone, enhancing reliability and the engine bay’s appearance.
This comprehensive silicone hose kit replaces ageing and brittle OEM rubber hoses in the FN2 K20Z4 engine bay. It includes 14 reinforced 4-ply silicone hoses and a complete 304 stainless steel worm drive clamp kit. The hoses are moulded to match the exact routing of the FN2 K20Z4, ensuring a precise fit and seamless integration with the cooling and vacuum systems.
Designed to withstand the demanding conditions of both road and track use, the hoses feature a durable black outer finish with a purple inner layer. This combination not only improves heat, UV, and chemical resistance but also tidies the engine bay for a professional look.
Exoracing Silicone Hose Kit Honda Civic FN2 K20Z4
The Exoracing Silicone Hose Kit Honda Civic FN2 K20Z4 delivers a significant upgrade in durability and reliability over standard rubber hoses. The reinforced silicone construction resists cracking, swelling, and degradation caused by heat and coolant exposure, which are common issues with ageing OEM hoses. With a 4.5mm thick wall and a working pressure rating of 85 PSI, these hoses maintain integrity under high temperature and pressure conditions, reducing the risk of coolant leaks and overheating.
The kit also includes a full set of 304 stainless steel worm drive clamps, which provide secure, corrosion-resistant fastening. These clamps ensure reliable sealing and ease of installation, preventing hose slippage and coolant loss over time. The combination of high-quality silicone hoses and durable clamps improves the overall reliability of the cooling and vacuum systems in the FN2 K20Z4 engine bay.
Performance & Benefits
Upgrading to the Exoracing Silicone Hose Kit Honda Civic FN2 K20Z4 enhances cooling system reliability, which is crucial for maintaining optimal engine performance. The silicone hoses withstand extreme temperature ranges from -54°C to 260°C (-65°F to 500°F), making them suitable for both everyday driving and track conditions. Their resistance to UV rays, water, and ageing helps preserve the hoses’ condition and appearance over time.
In addition to improved durability, the black outer finish with a purple inner layer provides a neat and tidy engine bay appearance. This aesthetic upgrade is especially valued by enthusiasts who take pride in their vehicle’s presentation. The kit is also backed by an Exoracing lifetime warranty, offering peace of mind regarding product quality and longevity.
Application & Installation
This kit is specifically designed for the Honda Civic FN2 Type R fitted with the K20Z4 engine, matching the original hose routing exactly. It is not compatible with other K-series engines such as the EP3 K20A2, DC5, FD2, or K-swapped vehicles, nor with FN2 1.8 models.
Installation is recommended during coolant system maintenance, radiator replacement, or when refreshing worn hoses. The kit includes all necessary hoses and clamps, allowing a full system refresh in one job. Before installation, it is important to compare the hose layout on your vehicle to ensure compatibility, especially for left-hand drive, imported, or engine-swapped cars.
While moderate DIY skills suffice, professional installation is advisable if you are unfamiliar with draining, refilling, and bleeding the coolant system. The kit installation involves draining the coolant, removing old hoses one at a time, fitting the new silicone hoses with the supplied clamps, and properly refilling and bleeding the cooling system to avoid airlocks.
