KIBBLEWHITE Intake Spring Kit 30-33200

Factory intake valves wear out—it's physics. The KIBBLEWHITE 30-33200 stainless steel conversion kit replaces them with components engineered to last 4x longer, keeping your valvetrain reliable through countless heat cycles and high-RPM demands. If you're serious about extending engine life without sacrificing performance, this is the upgrade that pays for itself in longevity.

This isn't a universal solution—KIBBLEWHITE designed each application-specific kit using FEA software and proprietary spring analysis to ensure perfect harmony with your cylinder head. You get forged stainless steel intake valves, premium heat-treated wire springs, and ultra-light titanium retainers, all engineered as a system and manufactured in the U.S.A.
