Overview
The Radium Engineering Fluid Lock Dual Catch Can Kit provides advanced crankcase ventilation filtering for turbocharged EJ-series engines in the 2002-2021 Subaru WRX and STI. By preventing oil mist from entering the turbo inlet and top-mount intercooler, it prevents octane degradation and ringland failure under high boost.
Features
- Comprehensive dual catch can protection for high-boost Subaru EJ20 and EJ25 turbo engines
- Filters both valve cover breather lines and crankcase PCV system to protect intake tract
- Mounts cleanly using chassis-specific laser-cut bracket on the Subaru strut tower area
- Anodized billet aluminum canisters feature removable internal stainless steel condensing media
- Includes high-temperature fuel and oil resistant hoses, 10AN fittings, and dipsticks
