Ferrea Honda Type-R K20C1-Turbo Single Spring Kit

This is the Ferrea Single Spring Kit specifically for the Honda Type-R K20C1-turbo engine, part number KT4033. If you're building a high-performance K20C1-turbo for track use or serious street driving, you know how critical valve control is, especially when you start pushing boost and RPMs. These springs are designed to keep your valves in check under those demanding conditions, ensuring reliable operation and preventing valve float at higher engine speeds.

Ferrea is well-known for making strong valvetrain components, and this kit is no exception. They use high-grade materials and advanced manufacturing processes to create springs that can handle the increased stress of a turbocharged engine. The single spring design is a popular choice for many turbo builds because it offers a good balance of performance and simplicity. This kit is engineered to work with the factory valve angles and retainers, making it a more straightforward upgrade compared to some other setups. You'll find that the improved spring pressure helps maintain proper valve seating, which is essential for consistent power delivery and engine longevity when you're running significant boost.

When you're installing these, make sure you have the right tools for valve spring compression and replacement. It's a job that requires attention to detail to ensure everything is seated correctly. This kit is designed to be a direct replacement for your stock springs, but it's always a good idea to refer to the manufacturer's installation guide for specific torque values and procedures. This Ferrea spring kit is a solid choice for anyone serious about getting the most out of their K20C1-turbo engine.
