What intake manifolds are available?
None are available for the B6 engines, however B8 (1.8l SOHC) owners can swap out their restrictive intake manifold in favor of the BP’s (1.8l DOHC) manifold. You will need an RPM activation trigger to power the VICS solenoid as well as some dyno tuning. BP engine owners can use the intake manifold from the 323 GT-R’s BP-ZET engine (part # BPC8-13-100). The GT-R’s intake manifold does flow a lot better and is specifically designed for turbo applications, but nothing else is known about it. Do note that the GT-R’s and GT-X’s intake manifold does not have VICS. MazdaSpeed did make a 4 barrel throttle kit for the Miata BP-ZE but you maybe able to rotate the plenum to have the air hose inlet facing the other way so that an air air filter assembly can be used in the stock location. The kit is no longer made but it was last seen being sold used for around $1300. The part number is 9EP5-13-000. It has 43mm throttle bodies, and 40mm velocity stacks. 2nd generations: Sorry, there are none for t
