Ferrea Toyota 1FZFE Double Spring-Special Alloy Valve Spring - Set of 24

Crafted from a special alloy, these Ferrea valve springs are built to handle the demands of a high-performance Toyota 1FZFE engine. This set includes 24 individual springs, enough to replace all the valve springs in your engine. Designed to provide necessary seat and open pressure to ensure valves close reliably, even at high RPMs, preventing valve float common with stock springs under forced induction or aggressive camshafts. The special alloy offers improved strength and resistance to fatigue. Suitable for stock or performance camshafts, maintaining proper valve timing and preventing power loss.
