Overview

We found the Pro R really likes to push oil out the crank case breather into the intake tract. This catch can greatly reduces the amount of oil/fuel vapor found in your intake and is nearly a must have modification.

Catch Can fits all 2022-Up Pro-R 4 Cylinder Models

• We found the Pro R really likes to push oil out the crank case breather into the intake tract. This catch can greatly reduces the amount of oil/fuel vapor found in your intake and is nearly a must have modification.
• Removes excessive oil vapor from your intake manifold
• Helps eliminate reduction of octane from excessive oil vapor in your intake during aggressive driving – when it matters most
• Helps reduce build-up of carbon on the pistons, valves, and combustion chamber
• Closed loop catch can is vented back into the intake for a sealed system and is best for all off-road situations. This also uses intake suction to help scavenge pressure from the bottom end. This is our preferred design for the Pro R
• Open loop catch can (Picture #2) is vented to atmosphere, and not back to the intake. This simply has a 1″ filter on it with only 1 side port on the can. This is great as it completely eliminates crank case vapors from the intake, but does not scavenge and is more maintenance/messy as it has a filter for venting the can.
• Both cans have our custom baffle design to keep oil slosh down in the can which is critical for off road applications
• Made at the AA fabrication facility in the USA
