Upgrade Your B58 Catch Can System with a True Dual-Vent Solution
Take your B58 BMW or Supra’s crankcase ventilation performance to the next level with the BMS Oil Filler Cap Dual Vent Connection Kit = the missing link for ultimate catch can and engine efficiency.
This precision-machined billet cap replaces the factory oil filler cap and creates a second dedicated exit point for dirty PCV gases. That means both the crankcase vent and the valve cover breather can now be routed into your oil catch can. Twice the inputs into your catch can means twice the oil vapor capture, keeping harmful oil mist out of your intake tract. Cleaner air, cleaner intake valves, and a more efficient PCV system, more efficient engine, it’s a simple upgrade with major payoffs.

Why This Matters:
- Double the Captured Flow: Adds a second breather port for PCV/vapor extraction so you pull more blow-by gasses into your catch can.
- Reduces Piston Resistance: This creates a slight negative pressure (vacuum) in the crankcase, reducing the resistance the pistons face as they move, improving fuel economy and performance.
- Manages Pressure: "Blow-by" gases (unburned fuel, air, combustion byproducts) get past piston rings into the crankcase, creating pressure.
- Cleaner Combustion Air: Reduces oil vapor recirculation that leads to intake valve carbon buildup.
- Maximized Catch Can Efficiency: Works with the BMS catch can to let it do more of its job.
- Perfect For: Anyone running a B58 BMS oil catch can looking to squeeze every bit of performance and protection from their PCV system, especially on tuned or high-boost builds.
