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.
