Radium Engineering Crankcase Catch Can Kit - Ford Focus RS

Supplied 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 in line 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. For the ultimate in-engine protection for your RS, we recommend the 20-0328 Dual Catch Can System. The 20-0328 kit utilizes both the "Crankcase" and "PCV" catch can kits.Add the Radium Catch Can Drain Kit for easy service. Prevents oil buildup in the intake and intercooler system walls, throttle body, intake manifold, etc. Excessive oil collection can be an indicator of a damaged engine.
