Radium Engineering Dual Catch Can Kit – Mitsubishi EVO VIII and IX

One often overlooked but critical component for any high performance modified vehicle is the addition of a crankcase catch can. By installing a Radium Engineering Crankcase Dual Catch Can Kit (20-0118) in your Mitsubishi EVO VIII or IX you’ll be sure you’re catching all of those nasty crankcase vapors and blow-by before they get into your combustion chamber. With the dual catch can kit you will get both the Crankcase Catch Can and PCV Line Catch Can Kits.

​

The Crankcase Catch Can Kit installs immediately underneath the LH strut tower and plumbs in-line with the crankcase vent hose. This is the hose that connects from the port on the valve cover to the turbo air intake pipe. During low engine loads, this hose experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience vacuum and would normally be drawing unwanted crankcase vapors, unspent fuel, and oil sludge into the air filter intake pipe, turbocharger compressor, etc. For instance. if you are finding oil accumulation stuck in the intercooler, this catch can is a necessity as oil will lower the thermal efficiency properties of the heat exchange process. Below is a picture of the crankcase vent catch can kit with the strut bar in place.

Crankcase Catch Can Kit Includes:

• Billet oil catch can with integrated condenser and dipstick
• Laser cut powder coated LH mounting bracket
• Anodized aluminum hose ends and adapter fittings
• Enough black 3/8″ PCV hose for custom applications
• Stainless steel mounting hardware

The PCV Catch Can Kit is compatible with all EVO VIII and IX models. It installs immediately behind the RH strut tower and plumbs in-line with the PCV hose. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV “check” valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience “metered” vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. Because Radium catch cans are pressure sealed, they are great for boosted applications as well so connecting to the intake manifold is permitted and will withstand any boost level.

PCV Line Catch Can Kit Includes:

• Billet oil catch can with integrated condenser and dipstick
• Laser cut powder coated RH mounting bracket
• Anodized aluminum hose ends and adapter fittings
• Enough black 3/8″ PCV hose for custom applications
• Stainless steel mounting hardware
