HKS 03-6 Adjustable Cam Gear – for Evo 8 and 9 (03-6)

Designed for precise valve-timing adjustment on Mitsubishi Lancer Evolution VIII and IX platforms, this HKS adjustable cam gear (03-6) enables tuners and enthusiasts to fine‑tune camshaft timing to optimize midrange response, improve throttle transient behavior, and refine the powerband for performance engines. As a direct-fit performance component for Evo 8 and Evo 9 engines, the unit works with existing camshafts and timing systems to provide repeatable timing changes for dyno tuning, track use, or spirited street driving.
