Mitsubishi EVO III 3 CE9A 4G63T

Twin Cam, 16 Valve, Single Turbo

Set 16 Uprated Valve Springs

For Higher Revs & Big Cams

Genuine HKS

Set of Genuine HKS Uprated Valve Springs for 4G63 Engines As valve train dynamics change with the use of high performance cam profiles and greater lift, stiffer valve springs are needed to optimize valve movement. When changing to a high lift cam, stock springs cannot match the increased valve train movement.   A stringent shot-peening and heat treatment process is applied to the HKS valve springs to provide durable and consistent spring rates over time. Applications with high revving engines will benefit from HKS valve springs, as the risk of valve-float and coil-bind is greatly reduced due to their specific design and construction.

Forged Pistons & Conrods w. ARP Rod Bolts Also Available
