10mm thick 5053 Aluminium CNC cut inlet manifold adapter plate to suit the Ford/Mazda Duratec 2.5 engine. This sandwich plate allows the fitment of a standard OEM 1.8 or 2.0 inlet manifold to the 2.5 head. By offering the 2.0 profile on the manifold side (tapering out to the taller 2.5 port profile on the head side) the sealing issues sometimes encountered when bolting straight up to the head are eliminated. 

This plate can also be used if fitting aftermarket inlet manifolds that have been designed for the 2.0 engine, however alternative fasteners may be required. 

The kit consists of:

1 x Duratec Inlet Adapter Plate

Options:

1 x 1mm thick heavy duty Duratec 2.0 Inlet Gasket

1 x Duratec 2.5 Inlet Gasket

Fastener Kit (50mm long Hex Head Screws for thick flanged inlets such as the MX5 NC)
