Detailed Product Description

The VAICO V10-6458 engine crankcase pressure regulator valve is a critical component in the emission control system, specifically within the crankcase ventilation system. Manufactured with a durable polyamid 6.6 housing, it ensures resistance to heat and chemical exposure common in engine environments. The valve’s pressure-controlled operation helps regulate crankcase pressure by allowing gases to vent properly, preventing pressure buildup that can lead to engine performance issues.

Its breather valve design, combined with high-quality Fpm and acm seal materials, provides reliable sealing and long service life. The compact dimensions (42 mm height, 188 mm length, and 84 mm width) allow for precise fitment on the cylinder head of compatible vehicles. This part is engineered to meet the specifications required by Audi and Volkswagen models such as the A3, Eos, Jetta, and TT Quattro, ensuring proper integration with the engine’s emission control system.
