Radium Dual Catch Can Kit (04-2021 STI/ 02-2014 WRX)

SKU: 20-0608 Category:


An oil catch can is essential for engine protection from elevated levels of crankcase blow-by oil that accumulate during aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance by depositing oil on the inside of the induction system, intercooler, intake manifold, etc. 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.

This kit contains two independent catch cans, each plumbed into different parts of the PCV system. The cans do NOT vent to atmosphere (VTA), and instead maintain the factory plumbing strategy. This closed-loop system routes clean filtered air back in through the engine promoting negative crankcase pressure for optimal performance. Furthermore, closed loop systems prevent unwanted oil vapors from being detected in the cabin. Catch cans must be maintained and emptied on a regular basis.

The catch cans are not compatible with RHD vehicles as the kit installs on the RH strut tower. As shown below, the low profile design only extends 4.8″ (122mm) off the strut tower.

*For 02-05 Subarus with a cable-actuated throttle body, our Cruise Control Relocation Bracket must be used.
*For RHD vehicles, our Universal Dual Catch Cans must be used for custom mounting and plumbing.

Optional Petcock Drain (20-0024) 

  • Anodized -4AN ORB Barbed Fitting
  • Nylon ¼” Barb Mini Ball Valve
  • CV Compliant Rubber Hose

Sold seperately, these kits can be used to remotely drain the catch cans without the need to unscrew the canister bodies. There is an option to put the remote drain kit on one or both catch cans. This is recommended for users that need to drain the catch can contents quickly and easily.

NOTE: Not compatible with the forward most catch can if using a Radium 13-0110 Cruise Control Relocation Bracket, 02-05 Subaru.
