Discontinued item. Limited quantity.
The New Style Mugen Oil Cap is manufactured in the same factories where Mugen Formula racing engines are made, the end product has unparalleled quality - "Formula Quality".
This updated 'newer style' oil cap is slightly smaller in diameter (than the original Mugen formula oil cap) to help better fit Honda K-series iVTEC engines. The cap will fit any non K-series Honda engines as well.
