Blow Off Valves and Accessories

The Blow Off Valves and Accessories collection features essential components for turbocharged engines, designed to manage excess pressure and protect your turbocharger. A blow off valve, sometimes referred to as a blowoff valve, is a crucial part that addresses the surge of pressurized air created when the throttle closes rapidly. Without proper venting, this pressure can flow back into the turbocharger, causing stress and potentially shortening its lifespan.

These valves work by releasing that excess pressure into the atmosphere, which safeguards the turbocharger's internal components, like bearings and the compressor wheel, from damage. This not only improves the turbo blow off valve longevity but can also contribute to a more responsive throttle feel. When selecting a valve, factors such as flange type, valve size, and spring pressure are important for proper fit and performance. Brands like the HKS blow off valve and TiAL blow off valve are well-regarded options. While a wastegate also plays a role in turbo systems by regulating maximum boost pressure, a blow off valve's primary function is to efficiently release excess pressure for turbo protection.
