Cylinder head fan Pionýr D38 mm - Tuning

Tuning cylinder head with fan fins, designed for Pionýr engines with a bore of D38 mm . The design with an anti-knock slot and a centrally located spark plug maximizes performance. It is recommended to use a spark plug with a thread length of 19 mm and an appropriate heat value (e.g. Brisk L15C or NGK B7ES). The head is sand cast, which makes the surface structure rough.
