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.
