Ramair Performance Foam Air Intake Kit for VW Up, Skoda Citigo & Seat Mii – SR-128
The Ramair SR-128 is a direct replacement induction kit designed to improve airflow into the engine of the VW Up, Skoda Citigo, and Seat Mii. It replaces the factory airbox – which is built with cost and noise reduction in mind rather than performance – with a freer-flowing foam filter setup that lets the engine breathe more efficiently.
The result is a modest but noticeable improvement in throttle response and engine breathing, particularly useful on the 1.0 MPI engine where every bit of efficiency counts. It also produces a more direct intake sound under acceleration, which many drivers find a welcome addition in a car of this size.
What’s Included
- Twin-layer foam performance air filter
- T304 stainless steel cage support structure (holds the filter firmly in shape)
- Full fitting hardware – all nuts, bolts, and brackets required
- Step-by-step fitting instructions
About the Filter
Ramair’s foam filters are made by hand in the UK and use a twin-layer open-cell foam construction. This design allows a high volume of air to pass through while still filtering out dust and debris that could damage the engine over time. Unlike paper filters, the foam element can be cleaned with warm soapy water and reused, making it a long-term investment rather than a consumable. Ramair back every filter with a lifetime guarantee against manufacturing defects.
Installation
Fitting is straightforward and is designed to be a like-for-like swap for the original airbox. No specialist tools are required, and full instructions are included in the kit. The SR-128 is built to fit neatly within the existing engine bay space, so no cutting or modification to the vehicle should be necessary.
Important: Always ensure the filter is fully dry before refitting after cleaning. Fitting a damp filter can cause issues with the mass airflow sensor (MAF) – a component that measures the air entering the engine – and may affect engine performance or trigger warning lights.
This kit is designed to fit the 2011-2021 VW Up, Skoda Citigo, and Seat Mii with the 1.0 MPI engine. To confirm fitment for your specific vehicle, please use the vehicle lookup tool on this site or check the Vehicle Fitment tab for the full compatibility list.
