Description
Radium Crankcase Catch Can Kit Fluid Lock — Honda S2000 AP1/AP2 1999-2009
An oil catch can is essential on any performance vehicle to protect the engine from elevated crankcase blow-by accumulated during aggressive driving. Excess oil-saturated air recirculating back into the intake stream degrades combustion efficiency, fouls intake valves, and reduces thermal efficiency in intercooled applications. Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick.
The Radium Crankcase Catch Can Kit Fluid Lock 20-0097-FL runs inline with the 1/2" valve cover breather port. At high load (WOT), this hose experiences vacuum and would otherwise draw crankcase vapours, unspent fuel, and oil sludge into the air filter intake pipe. For turbocharged or supercharged applications, this catch can is a necessity — oil accumulation in the intercooler significantly reduces heat exchange efficiency.
This kit operates as a closed-loop system — it does not vent to atmosphere (VTA), making it emissions and track legal. Clean, filtered air is routed back through the engine to promote negative crankcase pressure for optimal performance, while preventing oil vapours from entering the cabin.
Compatibility Note: This kit is designed for 2000-2009 RHD and 2006-2009 LHD Honda S2000 models. It is not compatible with 2000-2005 LHD models unless the cruise control module is removed.
For the ultimate in engine protection, Radium recommends pairing this kit with the PCV Catch Can Kit 20-0098-FL, or purchasing the complete Dual Kit 20-0099-FL.
Suits: Honda S2000 AP1 (1999-2004), Honda S2000 AP2 (2005-2009)
