Ferrea Acura/Honda B18/B16 Endurance Dual Spring Kit

This is the Ferrea KT4001 Endurance Dual Spring Kit, specifically designed for Acura and Honda B18 and B16 engines. If you're building a high-performance engine for track use or serious street performance, these valve springs are a critical component for ensuring reliable operation at higher RPMs. They are built to handle the increased stresses and demands of modified engine setups, helping to prevent valve float and maintain proper valve train function when you're pushing the engine hard.

Ferrea is known for making well-built valvetrain components, and this kit is no exception. It features dual springs, which offer a more stable and controlled valve motion compared to single springs, especially at high engine speeds. This design helps to keep the valves seated correctly during aggressive acceleration and deceleration. The kit includes the springs themselves, along with the necessary retainers and other small parts needed for installation. This comprehensive approach means you get a matched set of components designed to work together, simplifying the process of upgrading your engine's valvetrain. When installing these, pay close attention to the manufacturer's recommended spring pressures and installation heights to ensure optimal performance and longevity.

Upgrading your valve springs is a key step when modifying your B18 or B16 engine for increased power and higher rev limits. This Ferrea kit provides the strength and reliability needed to support those modifications. Make sure to consult your engine build specifications and the included installation instructions to confirm compatibility with your specific camshafts and overall engine setup.
