Airtec catch-can kit specific for Ford Focus ST and RS mk2 and mk2.5 with external vent. This accessory allows you to vent the oil fumes into the atmosphere instead of having them circulate in the engine as per the original to be able to consume them. In addition, it features a modified filter housing that eliminates the problems of the original one due to breakages of the internal diaphragm, made and designed to be much more resistant and high-performance. Kit including everything needed for Plug & Play installation.
NOTICE: This modification may bring out problems previously masked by the original oil recirculation, as you may notice an accentuated leakage of oil fumes from the external vent due to the wear of the engine itself, therefore not dependent on the installation of the catch-can kit itself.
