25 089 17-S Valve Spring – Kohler OEM Replacement Valve Spring (Replaces 32 089 05-S)
The 25 089 17-S Valve Spring is a genuine OEM replacement valve spring designed for Kohler small engines. This valve spring maintains proper tension on the intake or exhaust valve to ensure correct opening and closing during engine operation. When valve springs become weak or worn, engine compression and performance can suffer — replacing them with the correct OEM spring helps restore proper valve function and reliable performance.
This part is a direct replacement for Kohler part 32 089 05-S, making it ideal for service or rebuild applications where the original valve spring has deteriorated or failed.
