Engineered for Bosch throttle body applications, these phenolic linen gaskets deliver reliable sealing in both OEM and performance-oriented builds. The 1/8" thickness strikes a balance between structural integrity and compressibility, ensuring consistent clamping load distribution across the gasket face. Phenolic linen construction offers superior thermal resistance, protecting downstream components from intake manifold heat soak while simultaneously dampening vibration transmission to the throttle body assembly. The material's inherent rigidity prevents gasket creep under thermal cycling, a critical factor in high-boost or extended-duration engine operation. Ideal for street and track applications where seal longevity and thermal management directly impact throttle response and component durability.
