Intake manifold adaptor for Mazda RX7 13B Engines. This adaptor enables you to fit a Series 6 upper intake manifold to a Series 4 lower intake manifold.

We have used the CAD design software to port match the upper and lower flanges for optimal air flow, and incorporated eccentric fasteners to compensate for the different bolt pattern of the two manifolds.

The manifold adaptor is manufactured from 6061-T6 aluminium and black anodised for light weight, great looks and corrosion resistance.

It also features individual o-ring seals around each port for superior reuseable sealing compared to factory paper gaskets. The manifold adaptor is supplied with all the high quality Viton o-rings and fasteners required for installation.

All machined components are CNC machined at our factory in Napier, New Zealand.
