    Product information

    Billet aluminum CNC milled adapter to convert your stock intake to a individual throttlebody setup.

    Your stock single throttlebody gets replaced with 4 individual 4AGE-20v Toyota throttlebodies.
    This adapter lets you bolt it all up without struggles.

    This billet piece is specially designed to be used on all 1.8 Mx-5 Miata engines.

    These adapters are redesigned and available since Januari 2024, featuring a steeper port design for improved flow and better transition into the stock ports. The throttlebody angle has been raised compared to the old design, resulting in a increase in power aswell as improved looks.


    This adapter works with 4AGE-20v silvertop throttlebodies.
    Blacktop itb's do fit but need a little modification with a dremel since the flange has a different design.

    The dual bolt pattern on the adapter lets you mount the adapter on 1.8 head, aswell as the 1.8VVT head.
