What is an ITB mx5?
Individual throttle bodies (ITBs) aren’t just for engine response and stylish looks—they make engines sound a whole lot better, too. This Miata is a great example. They’re a way to keep the linear power delivery the car is known for without adding weight and complexity to the engine.
Does ITBs increase horsepower?
Aside from a snappier throttle response, one of the main benefits of running ITBs is the additional horsepower that can be gained with them as more air is able to enter the engine at a quicker rate due to the air inlets being placed on each cylinder.
Are ITBs worth it?
In an engine with ITBs, atmospheric pressure builds outside each cylinder, so when you open the throttle, air enters instantaneously. ITBs also help reduce pumping losses at partial throttle. The difference in throttle response is worth it in high-performance engines, but for normal street cars, it’s unnecessary.
Is ITBs legal?
yes their are city you can register in that do not have smog in CA… this is the little know trick around smog… The only legal ITB setup in CA would be from a BMW M-car which come stock with ITB’s.
Can you run ITBs with a turbo?
Yes you can fit throttle bodies and a turbo, but the gains of bodies over using an inlet plenum are not that big enough to justify doing so on a forced induction lump…
What are the benefits of ITBs?
ITBs make it possible to eliminate the intake manifold entirely and improve airflow. The air is able to be sucked into the engine more efficiently, and you can shape the velocity stacks to fit your purpose.
Can a Mazda MX5 be converted to ITB?
The ME221 is the ideal way to manage an ITB conversion in the MX5 due to the incredibly simple install into the original ECU case. This retains the original wiring loom and supports the factory sensors where appropriate. Further information about the ECU can be found on the Motorsport Electronics Website:
Which is throttle body kit for Mazda MX5 1.6 EFI?

What kind of DCoE does Mazda MX5 have?
These feature the AT Power patented Shaftless technology, meaning they will flow more air than a conventional shafted DCOE setup. The package also includes the ME221 Engine Management which comes as a plug in to the factory ECU case and connects to the existing wiring harness adaptor for the MX5.
What kind of manifold does Mazda MX5 use?
The manifold is manufactured from high quality aluminium with a precision Water Jet cut 10mm thick flange and TIG welded 45mm (Outside Dia) runners with a 3mm thick wall. All internal joints are fully ported/ground to ensure a smooth flow.
