Radium Engineering Crankcase Catch Can Kit Fluid Lock Honda S2000 (AP1/AP2)

Radium Engineering Crankcase Catch Can Kit Fluid Lock — Honda S2000 AP1/AP2 1999–2009

Radium Engineering produces CNC-machined billet aluminium catch can systems trusted by tuners and race teams running serious S2000 builds. The Radium 20-0097-FL Crankcase Catch Can Kit Fluid Lock is a direct bolt-on solution that protects your engine from oil-saturated blowby vapours recirculating through the intake — no cutting, drilling, or fabrication required. Designed specifically for the Honda S2000, this kit includes every bracket, fitting, and hose needed for a clean, complete installation.

This listing covers the Radium Engineering Crankcase Catch Can Kit Fluid Lock (SKU: 20-0097-FL), suited to the Honda S2000 AP1 (1999–2004) and Honda S2000 AP2 (2005–2009). This kit runs inline with the 1/2" valve cover breather port and operates as a closed-loop system — it does not vent to atmosphere, keeping it track and emissions legal. Related kits including the PCV Catch Can Kit (20-0098-FL) and Dual PCV/Crankcase Kit (20-0099-FL) are sold separately.

Important: This kit is designed for 2000–2009 RHD and 2006–2009 LHD Honda S2000 models. It is not compatible with 2000–2005 LHD variants unless the cruise control module is removed.
