This Valve Spring Kit for Honda/Acura DOHC applications includes carefully matched Dual Intake Springs, Single Exhaust Springs and Steel Retainers. The valve spring creation process is far more involved than most people realize. Selecting the right metal stock and creating the best design is not done by chance. COMP Cams® has developed a process that creates the highest quality valve springs available. Once the springs are created, we carefully match all necessary installation equipment so you get everything you need in one easy kit.
