Ferrea 2019+ Toyota Supra (B58) 29mm 5.96mm 99.80mm +.5mm OS Comp Plus Ext Valve - Set of 12

This set includes 12 Ferrea Comp Plus exhaust valves, specifically sized for the 2019 and newer Toyota Supra with the B58 engine. Each valve measures 29mm in diameter with a 5.96mm stem and a length of 99.80mm. These are a +.5mm oversize (OS) set, meaning they are designed to replace stock valves that have been machined to accept a larger valve. This is a common upgrade when rebuilding or modifying the engine's top end for improved airflow and performance.

Ferrea's Comp Plus valves are well-built using high-grade materials chosen for their strength and heat resistance, crucial for exhaust valve applications. The +.5mm oversize design allows for a larger valve head diameter, which can significantly increase the surface area for gas flow into the cylinder. This improved flow can lead to better combustion efficiency and a noticeable increase in power, especially when paired with other engine modifications. The precise sizing and construction ensure they fit right into heads that have been properly prepared for them.

When installing these valves, it's important to ensure the cylinder head has been machined to the correct dimensions for the +.5mm oversize. This is a critical step for proper sealing and performance. This set is intended for enthusiasts looking to maximize the breathing capabilities of their B58 engine. Always refer to the manufacturer's installation instructions for detailed guidance on proper fitment and any associated components needed for your specific build.
