The Kyosho 74032-02 under head is manufactured for the KE25SP engine and serves as a critical sealing component. By keeping the cylinder-to-head joint sealed, it supports even running and helps prevent leakage that can affect performance.
Made to match KE25SP specifications, this under head installs as a replacement part without modification on standard engines. Its accurate build helps preserve compression and consistent combustion in everyday use and track sessions.
Installation is straightforward. Clean the contact surfaces thoroughly before fitting and tighten fasteners evenly. Inspect the seal during routine engine checks and swap the under head at the first sign of seepage.
