Focus RS 2016-2017Supplied exclusively by Radium Engineering, their Crankcase Catch Can Kit for the Ford Focus RS attaches to the high pressure fuel pump (HPFP) mount on the back of the cylinder head. Because the ST uses a different HPFP than the RS, this kit is only compatible with the RS .
This catch can runs inline with the crankcase breather port. At low loads it experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience high flow out of the crankcase. This would normally lead to oil and sludge accumulation in the air filter intake pipe. Oil accumulation will occur in the intercooler which lowers the thermal efficiency properties of the heat exchanger and leads to decreased performance.
