The VTT B58/S58 Head Port Block-Off kit is designed to either seal off the factory head ports used by the OEM low-side PCV system. These ports in the cylinder head utilize engine vacuum to evacuate crankcase gases, but in the process, can allow oil to enter the intake manifold, leading to valve carbon buildup and other performance issues over time. The Block-Off kit offered by VTT completely seals the factory head ports to prevent oil intrusion and unwanted vacuum leaks. This kit does NOT require any tapping, meaning no metal to get into the engine, etc. You simply tap the plugs into place. Key Features Eliminates oil draw-through into the intake manifold Prevents carbon buildup on intake valves Utilizes precision-machined plugs for boost sealing Fully reversible — Block-offs can be removed if needed No tapping is required. Easy install, by tapping the blocks into place.

Keep crankcase vapors in check and your intake air clean with the BMS Oil Catch Can Oil Filler Cap Dual Vent Connection Kit for the Gen2 B58. This upgrade ditches the flimsy factory venting in favor of a precision CNC-machined billet oil filler cap and dual-vent fittings engineered to handle increased crankcase pressure under boost. By diverting oil-laden vapors into a catch can instead of back through the intake, this system helps minimize carbon buildup, reduces oily contamination, and promotes more consistent performance as power levels climb. High-quality hoses and fittings ensure a secure, leak-free install that won’t collapse under pressure and maintains a clean, OE-plus appearance in the engine bay. An easy, effective upgrade for B58 enthusiasts looking for cleaner operation, improved engine longevity, and proven performance-focused design

The VTT B58 Head Port Check Valve Kit is designed to convert the factory head ports used by the OEM low-side PCV system. These ports in the cylinder head utilize engine vacuum to evacuate crankcase gases, but in the process, can allow oil to enter the intake manifold, leading to valve carbon buildup and other performance issues over time. VTT's Billet Check Valve kit converts the head ports into a robust internal PCV system using precision-engineered check valves. These one-way valves allow vacuum to function as intended while blocking boost pressure from entering the crankcase or charge tract.
