What is valve float and how do these springs help?

Valve float happens when the valve train can't keep up with the camshaft at high RPMs, causing the valve to bounce instead of closing properly. These Skunk2 springs have higher seat and open pressures to ensure the valves close firmly and maintain stability even above 10,000 RPM.

What is the difference between seat pressure and open pressure?

Seat pressure is the force exerted by the spring when the valve is fully closed. Open pressure is the force exerted when the valve is fully open. These values indicate how strong the spring is at different points in its cycle, ensuring proper valvetrain control.

Are these springs suitable for a stock D-series VTEC engine?

While these springs are designed for high-RPM use and are a popular choice for modified engines, they can also be used in stock D-series VTEC engines to improve valvetrain stability. They are manufactured from high-quality materials for reliability.
