HKS Valve Spring Kit for 4A-GE (16 Valve Only)

Notes:

• Valve Spring for High RPM Engines

  Valve spring performance is very important for valves to follow accurate cam profile.

  1. Compatible with High RPM Engines

• As engine rpm rises, valves must open and close in a shorter time and so requires stronger Valve Springs in order to apply sufficient pressure.

  2. Ensuring Close-Contact

  When changing to high lift cams,

• proper contact between the valves and the cams can be lost which leads to valve float. HKS Valve spring use the highest quality materials, heat treatment and shot-peening to create a high durability spring with low inertia.

  Not

• compatible with 5 valve. Lift design 8.1mm.
