Ford ST170 Throttle Bodies & ME221 Base Map ECU Package


This is an ITB kit using AT Power Billet Direct-To-Head Throttle bodies including air horns, linkage, fuel rail, 3D printed extensions on the Oval throttle bodies, and being direct to head the manifold is part of the assembly – which is the correct port sizing for the ST170 (larger than a normal Zetec).

The package also includes the ME221 Engine Management with full Plug-n-Play loom for the ST170, which retains full closed-loop VVT control to get the best torque curve possible – no sacrifices!

Typical power on a good condition ST170 engine will be 190-210bhp (using supporting mods such as high flow exhaust system etc.)

Delivered fully assembled with a choice of Linkage orientations & Billet aluminium Fuel Rail, with a choice of Inlet Lengths & TPS choices calibrated to the options available from the AT Power range. Available in 18 anodised colour options.

Optional extras include new 330cc Pico injectors,  a Magnetti Marelli throttle position sensor and ITB filter and backplate

Motorsport Electronics have full engine dyno and rolling road facilities on site as well as an ever growing list of tuners across the UK, Europe and Worldwide – see Motorsport Electronics Tuning Partners for your nearest approved agent.
