KIBBLEWHITE Intake Spring Kit 30-33250

Factory titanium intake valves degrade under sustained high-RPM operation, leading to valve float, loss of compression, and costly head work. The KIBBLEWHITE Intake Spring Kit 30-33250 replaces these components with stainless steel Black Diamond valves and precision-engineered springs that extend valvetrain life up to 4x longer while maintaining optimal valve control across the entire rev range. If you're running your engine hard—whether on the track or in competition—this conversion eliminates a common failure point and delivers the reliability serious racers demand.
