Supertech BMW S14 16V/S38 24V Dual Valve Spring Kit

Constructed from high-tensile chrome silicon wire, this dual valve spring kit from Supertech is built to handle the demands of high-performance BMW engines like the S14 16V and S38 24V. The chrome silicon material offers excellent fatigue life and consistent spring rates, which are crucial for maintaining proper valve control at higher RPMs and under increased boost or nitrous conditions. This kit is designed to replace your stock valve springs, providing the necessary support for more aggressive camshaft profiles or forced induction setups.

Each spring in this kit is precision wound and heat-treated to ensure durability and consistent performance over time. The dual spring design offers increased seat pressure and open pressure compared to single springs, which helps prevent valve float—a condition where the valve train can't keep up with the camshaft's speed, leading to potential engine damage. This improved control is essential when you're pushing your engine beyond its original specifications. The kit includes all the necessary springs to service your engine's cylinder head, ensuring a complete replacement for critical valve train components.

When installing this kit, it's important to ensure your camshafts and retainers are compatible with the increased spring pressures. Proper installation and valve spring seat height adjustment are key to achieving optimal performance and reliability. This Supertech kit is a solid choice for enthusiasts looking to build a more robust and responsive engine for track use or spirited driving.
