Radium’s single catch can kit for 2015–2018 Ford Focus ST interfaces with the crankcase vent line and includes the Fluid Lock catch can. It installs with minimal modification and aims to trap oil and moisture before they reach the intake tract. The bolt‑in kit offers a practical way to reduce intake contamination and maintain cleaner intake system operation.
