This TOPRAN crankcase ventilation kit, part number 121 638, is designed to maintain the correct pressure within your engine's crankcase.

Over time, crankcase ventilation components can become clogged or damaged, leading to increased internal pressure and potential engine issues. This kit provides a direct replacement for your original part, ensuring a seamless installation and restoring the ventilation system to its intended function. By effectively removing blow-by gases from the crankcase, this kit helps to keep your engine oil cleaner for longer and contributes to more efficient combustion.
