Inner Head and Tuning Impact

This Kyosho spare is the inner head component for the KE21V engine, supplied as a direct replacement for servicing or performance adjustments. It occupies the combustion chamber area and provides the sealing surface inside the engine head assembly, useful during rebuilds or tuning swaps.

Because the inner head determines chamber shape and sealing, it has a measurable effect on compression and engine response. When using a replacement for tuning, inspect mating faces and gaskets and confirm precise alignment with the head flange to secure repeatable results.

The part is listed for the KE21V engine platform; confirm part number Kyosho 74035-02 before purchasing to ensure correct application and avoid fitment assumptions.

Use this inner head to preserve chamber integrity during KE21V tuning or to restore head geometry to factory condition.
