Titanium intake valve face recession is the most commonly repeated expensive repair on todays late model 4-strokes. Kibblewhite stainless valves and spring kits have proven to extend the intake life by as much as 3x over the stock components. Kits include everything needed to convert intake from titanium to stainless steel valves in one convenient package. Valves are Premium Grade KPMI Black Diamond stainless 1-piece forgings. Springs are super-clean chrome silicon wire that has been heat-treated, stress relieved and shot peened. Economical solution for a low hour head with good exhaust components.
