An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance.

Radium Engineering offers several completely independent oil catch can kits for the Evo X that are sold individually or together using the menu above. The first type do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors into the cabin. The Crankcase VTA kit does not recirculate crankcase gasses back through the engine and is intended for race vehicles dealing with a large amount of blow-by gasses.

The Crankcase Catch Can Kits install immediately behind the LH headlight 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. On 2008-2009 EVO X models which use the "metal" valve cover, the hose is 3/8" (10mm) and requires P/N 20-0106-08. On 2010-2016 EVO X models which use the "plastic" valve cover, the hose is 1/2" (13mm) and requires P/N 20-0106-10. These aforementioned kits were designed with the OEM intake system. If an aftermarket intake is installed, consider purchasing 20-0300 Alternate Location Mount separately.

During low engine loads, this crankcase vent 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. Oil coating the inside of the intercooler will lower the thermal efficiency of the intercooler. 20-0181 Crankcase VTA Catch Can Kit:
