This installation kit was specifically designed for the 2008-2009 Mitsubishi Lancer Evolution X.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. Unlike many catch cans on the market, this catch can features an integrated oil separator that accelerates oil condensation. This cleans the PCV gasses and reduces the oil build-up on the inside of the intake tract and intake manifold and intercooler.The stainless steel filtration media is cleanable and reuseable. The catch cans act as a filter and collect the oil and other sludge and keep it out of vital engine components.Features:-Effectively raises the octane and increased engine performance from cleaner inlet air -Prevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc. -Excessive oil collection can be an indicator of a damaged engine.-Lowers hydrocarbon emissions -Capacity: 6 fluid ounces -Height (without fittings): 5 inches -Outside Diameter: 2.45 inches EVO X CATCH CAN KIT DETAILSRadium Engineering offers two completely independent oil catch can kits for the Evo X that are sold individually or together using the drop down menu above. They 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 PCV Catch Can Kit (shown below) installs immediately behind the RH headlight 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. Note: Because the 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.The Crank Case Catch Can Kit (shown below) installs immediately behind the LH headlight and plumbs in-line with the crank case 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 and intercooler system. The Radium oil catch can keeps that from happening.For the ultimate in engine protection, Radium recommends installing both catch can kits.PCV Kit Includes:-Radium billet oil catch can with integrated condenser and dipstick-Radium laser cut powder coated application specific mounting bracket-Anodized aluminum hose ends and adapter fittings-Rubber hose to mate to custom applications -Stainless steel mounting hardware Crank Case Vent Kit Includes:-Radium billet oil catch can with integrated condenser and dipstick-Radium laser cut powder coated application specific mounting bracket-Anodized aluminum hose ends and adapter fittings-Rubber hose to mate to custom applications -Stainless steel mounting hardware PETCOCK DRAIN KIT OPTION-Anodized -4AN O-ring barbed fitting -Nylon ¼” barb mini ball valve -6ft high temperature rated 1/4" rubber hoseThis kit, sold seperately, can be used to remotely drain the catch cans without the need to unscrew the canister body.
