The inlet manifold on our 442.8 bhp daily-driven Fiesta ST180
Pumaspeed Racing Fiesta ST180 Alloy Adjustable Volume Inlet Manifold. Unlock the true potential of your 1.6 EcoBoost’s breathing with a cast alloy, tune-able inlet manifold: adjustable plenum volume, O-ring sealed between every layer, and a direct bolt-on in place of the factory plastic manifold. It is the same manifold, with the red coating option, that sits on our red ST180 on the MAXD-OUT dyno at 442.8 bhp – a car that still does the Monday commute.
Ours, in red: the Pumaspeed Racing manifold in the engine bay of the 442.8 bhp G25-550 ST180.
Watch it work – sound on
The headline 442.8 bhp run on our MAXD-OUT development dyno.
Why the plastic one has to go
The factory plastic manifold is a known weak link on a tuned ST180. Heat cycling and extra boost fatigue it until it cracks or leaks – and a boost leak costs you power, smoothness and your peace of mind. Ours is cast from high-grade alloy, so it holds its shape and its seal however hard the engine is worked. It is built to take the extreme engine bay temperatures and pressure spikes that would shatter a plastic manifold.
Engineered, not just cast
This is not just a replacement part – it is a ground-up re-engineering of the EcoBoost intake, designed to remove the restrictions of the stock setup. Free of the limits of mass-produced plastic moulding, we used CAD modelling to optimise the runner length and internal volume. The result smooths airflow, reduces turbulence and gives every cylinder a balanced, high-velocity air charge – exactly what matters on hybrid turbos and high boost pressures, where the engine is being pushed to its limits.
Tune the volume, keep the seal
The plenum is modular. Add a 10 mm, 15 mm or 20 mm volume spacer to create more internal volume and much more torque. The 20 mm spacer is the one we recommend.
O-ring seals between the layers – every joint in the stack is sealed with large O-rings, so adding volume never means adding a boost leak.
Proven gains – in our own testing on a street setup, the 20 mm spacer was worth 20 bhp and 20 Nm.
Your build, your choice – more volume generally favours top-end power; a tighter plenum sharpens low-down response. Not sure which? Call us and we will tell you what we would run on your car.
Proven on the dyno, not just on paper
Our red ST180 runs this manifold as part of a deliberately off-the-shelf build: Pumaspeed blue-top linered engine, mild cams, Pumaspeed 38% uprated injectors and the Pumaspeed G25-550 Direct Bolt-On Turbo Kit

A true bolt-on
Designed as a direct fit: it works with your existing fuel rail, sensors and throttle body. No cutting, no fabrication – just a stronger, better-flowing manifold and an engine bay that finally looks the part, in premium textured black or any of the colours below.
Build yours
Volume spacers – up to three: 10 mm (+£12), 15 mm (+£24) or 20 mm (+£30, recommended), all inc. VAT. Choose them with the options above.
Colour – Black, Red (as on our 442 bhp car), Blue, Yellow, Green, Baby Blue, Wrinkle Red, Wrinkle Black or Silver.
Fitting – fit it yourself, or let us fit it at our Wakefield workshop.
This is the manifold the ST180 was always meant to have.
