Mazda Mx-5 NC DTH 45mm kit

The Mazda Mx-5 NC DTH ITB Throttle Body Kit has been designed to fit directly into the Mazda MX-5 Mk3 NC car without making modifications to the engine bay.

The kit includes 48mm direct to head throttle bodies (ITB), super lightweight air horns, MAP rail with fitment for standard MAP sensor and utilises our Electronic throttle actuator and dual output throttle position sensor along with tps adaptor loom. There are also provision for the crank case vent input.

Jenvey Dynamics design, develop and manufacture all products in house often working with leading engine builders.  Uniquely, with our own foundry, all castings are created in the same factory that they are machined and built in.  Our cast systems are significantly lighter than fully CNC parts and all major components are backed up by rig tests of over 1 million cycles.  All our standard kits are proven but our throttle systems are extremely modular allowing bespoke throttle sizes and system lengths. Please order components individually for bespoke application.

This Jenvey kit requires an aftermarket ECU. We recommend Megasquirt and Motorsport Electronics plug in ECU.
