Supertech Honda NSX Dual Valve Spring Kit

The Supertech Dual Valve Spring Kit for the Honda NSX utilizes a unique dual spring design, with an inner and outer spring working in tandem. This setup is crucial for managing the high-RPM demands of performance engines, ensuring the valves close reliably even under extreme conditions. The springs are constructed from high-tensile chrome silicon wire, a material known for its strength and ability to withstand repeated stress without losing tension. This makes them a solid choice for enthusiasts looking to push their NSX's engine performance further.

This kit is specifically designed for the Honda NSX, meaning it's engineered to work with the factory valve train geometry and retainers, simplifying installation. The dual spring configuration offers increased seat and open pressures compared to single springs, which is essential for preventing valve float at higher engine speeds. This improved control over valve motion can lead to more consistent power delivery and better overall engine response, especially when the engine is operating at its upper limits. The chrome silicon material also offers good resistance to fatigue, contributing to the longevity of the component under demanding use.

When rebuilding or significantly modifying the top end of your Honda NSX, a robust valve spring kit like this is a fundamental component. It's designed to handle the increased stresses and higher rotational speeds that performance camshafts and engine tuning often introduce. Ensure you consult your service manual for proper installation procedures, as valve spring replacement typically involves specific steps for valve train assembly and timing. This kit is a key part of achieving reliable high-RPM operation for your NSX.
