Ferrea Nissan TB48DE 33.5mm 6.96mm 98.3mm 20 Deg Flo Stk Comp Plus Exh Valve - Set of 12 (Turbo App)

These Ferrea Competition Plus exhaust valves are built with a specific material choice: a high-strength, heat-resistant stainless steel alloy. This material is crucial for handling the intense temperatures and pressures found in turbocharged engines, especially when you're pushing your Nissan TB48DE beyond stock performance levels. Each valve measures 33.5mm in head diameter and features a 6.96mm stem, with an overall length of 98.3mm, designed to fit precisely within the engine's valve guides and work with your valvetrain.

The 'Comp Plus' designation means these valves are engineered for enhanced durability and performance under demanding conditions. The 20-degree valve seat angle is a detail that helps promote better sealing and gas flow compared to a standard 45-degree angle, which can be beneficial for turbo applications where efficient cylinder filling and exhaust scavenging are key. Ferrea is known for its well-built internal engine components, and this set of 12 valves is intended for a complete engine rebuild or upgrade where reliability and performance are paramount.

When rebuilding or upgrading your Nissan TB48DE, especially for forced induction, using valves specifically designed for those conditions is important. This set includes all 12 exhaust valves needed for the engine, ensuring a matched set for consistent performance across all cylinders. Always refer to your engine's service manual for specific installation procedures and compatibility details.
