Details
This is a complete, plug-and-play ITB conversion designed specifically for the Mazda MX-5 NC, supplied without engine management so you can run your own ECU.
The kit includes:
• Drive-by-wire (DBW) 48mm individual throttle bodies.
• Aluminium inlet manifold, machined in-house.
• 8-injector architecture (4 upstream, 4 downstream) for optimised atomisation and high-rpm performance.
• Cold feed Carbon PA6 airbox with a built-in high-flow replaceable air filter.
• Wiring loom for: 8 injectors, drive-by-wire, throttle position sensor and MAF sensor.
• Fixings and fittings — every required bracket, heat-resistant hose and high-tensile bolt is included, for a professional, secure installation.
• Injector Bung rail / Brake Servo Vacuum to replace OEM Fuel Injector Rail.
Please Note: The ME360 ECU is not included with this kit — we supply the ME360 separately, plug-in for the MX-5 NC with RRS base maps. The vacuum ports are built into the aluminium manifold using a 4-way internal porting system, which includes the injector bung rail without the vacuum port.
