The Civic Si has always been the sweet spot between daily Civic and full Type R, and this MST Performance cold air intake is tuned to that role. Engineered for the Si from 2017 on, it fits aluminium pipework and a heat-shielded washable nanofiber filter in place of the factory setup, giving the Si's turbocharged engine an induction voice and sharper feel that suit the badge — with a clean, reversible direct-fit install.
MST builds this kit for the Si rather than stretching the standard 1.5T part across both — the packaging matches the Si application from 2017 on. Non-Si tenth-generation cars use the standard Civic 1.5T kit, so pick the version that matches the badge on your boot.
For UK customers, prices include VAT, customs and delivery unless checkout states otherwise. For customers outside the UK, local customs and taxes remain your responsibility, and shipping is shown at checkout. If a shipping option is not available, email us and we will prepare a tailored quote.
Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
Order the standard Civic 1.5T kit for those cars instead — this version is engineered around the Si application from 2017 on.
Yes: clean it around every 20,000 km and replace at around 60,000 km. One element outlasts years of disposable filters.
Completely — it is a direct swap using supplied hardware, so the factory intake can be refitted whenever needed.
