Ferrea Honda Type-R K20C1 Turbo Single Spring Kit (Requires RR1006)

This kit includes the Ferrea KT4038 single spring set, designed specifically for the Honda Type-R K20C1 turbocharged engine. These springs are built to handle the increased demands of a boosted application, helping to ensure proper valve control at higher RPMs and under significant boost pressure. It's important to note that this kit requires the separate purchase of Ferrea's RR1006 retainers to complete the installation.

Ferrea is known for using high-grade materials, and these springs are no exception. They are constructed from a strong, durable alloy that resists fatigue and maintains its integrity under the extreme conditions found in a high-performance, turbocharged engine. The single spring design is optimized for the specific valve lift and spring pressures needed for the K20C1, aiming to provide reliable performance and longevity. Proper valve spring function is critical for preventing valve float, which can lead to serious engine damage, especially when pushing the limits of a turbocharged setup.

When installing this kit, ensure you have the correct tools and follow the manufacturer's recommended procedures for valve spring replacement. Because this is a performance-oriented component for a turbocharged engine, it's often paired with other upgrades to maximize the engine's potential and reliability. Always refer to the Ferrea installation guide for specific details and any additional components or procedures recommended for your application.
