The APR MS100100 Oil Catch Can System is designed to prevent excessive crankcase oil vapors from entering the intake system while the engine is under boost. In doing so, the system helps reduce oil pooling in the intercooler hoses, carbon buildup on intake valves, and the decrease in octane caused by oil vapors.
During an engine's combustion process extreme cylinder pressure is created. Some of this pressure ultimately becomes blow by gasses when it escapes the seal of the piston rings. As a result, crankcase pressure is generated and to prevent damage this pressure must be vented. Thanks to boost pressure, turbocharged engines produce more cylinder pressure than naturally aspirated engines. In turn, the requirement to effectively manage crankcase pressure is increased. More so, an increase in horsepower over stock comes through an increase in cylinder pressure, exacerbating the issue even further.
The factory system alleviates the pressure through a positive crankcase ventilation system, or PCV. Under light engine load, the PCV uses vacuum to help draw the gasses out of the crankcase and utilizes a cyclonic separator to draw the oil out of the gas. During heavy engine load, when boost pressure is present, that portion of the PCV is blocked off via a check valve and the gasses are sent directly to the inlet of the turbocharger. During this stage, little separation occurs and significant oil vapor is allowed to enter the intake tract which can cause the following:
Reduction in performance caused by a decrease in octane from oil vapors mixing with air/fuel mixture.
Reduction in performance caused by a decrease in airflow from excessive carbon buildup on intake valves.
Pooling of oil in the turbo, intercooler, intake tract hoses and manifold.
Unlike many catch can designs on the market, the APR system utilizes a track-proven four-staged baffling system. The baffles cause oil to pool at the bottom of the can, rather than the intercooler hoses. APRs brutal track testing has proven the system works as designed, catching oil in the can and leaving the return hose clean to the touch!
Removing the oil is a cinch! No tools or can removal/disassembly are required thanks to a quick drain valve and hose conveniently located at the bottom of the can. Furthermore, servicing the can is simple, thanks to the billet two piece design.
Benefits of the APR MS100100 Oil Catch Can System:
Drains in seconds No need for tools, removal/disassembly to drain the can.
Four-stage baffling system Excellent oil droplet capturing properties.
Compact, two-piece billet design Easy disassembly for recommended annual cleaning.
Abrasion resistant Buna-N lines Resists oil degradation, kinks and abrasion with an OEM appearance.
OEM Norma fittings Makes install and removal simple with an OEM appearance.
Discrete hose routing Hoses are routed out of sight for an attractive install.
Catches oil Oil pools in the can, not in the intercooler piping.
Increase performance Helps to reduce airflow restrictions and octane robbing oil vapors.
APR MS100100 Catch Can System Vehicle Fitment:
* Requires fitment of APR CI100033 Intake
APR MS100100 Manufacturing: The APR catch can is a two piece anodized billet aluminum design with an internal four stage baffle. The lines are constructed from Buna-N for abrasion resistance and feature Norma fittings for direct fitment on the OEM bungs.
APR MS100100 Catchcan Install: APRs Oil Catch Can system installs between the PCVs outlet and the inlet to the intake system. The supplied bracket and scratch resistant gasket allow the system to be installed on the required APR Carbon Fiber Intake System. The supplied hoses then connect and route out of site, for a clean and attractive install. The manifold PCV port must be blocked off, this can be accomplished with the APR boost tap. Fitment requires deletion of the engine cover. APR uses OEM Norma fittings for a direct snap fit to the OEM connection bungs. Basic hand tools are necessary for installation. Please observe all safety precautions and follow proper installation guidelines while working on your vehicle. APR MS100100 Install Manual
