商品系列: Valve Spring Kits
Valve springs are responsible for ensuring that the valves close properly, preventing valve float and other performance issues. Upgrading valve springs is a critical step in building a high-performance engine as stock valve springs often cannot handle the increased valve lift and higher engine speeds, leading to valve float and power loss.
