Ferrea Toyota 1FZFE 33mm 6.97mm 98.25mm 22 Deg Flo +1mm Competition Plus Exhaust Valve - Set of 12

This set includes 12 Ferrea Competition Plus exhaust valves, specifically made for Toyota 1FZFE engines. Each valve features a 33mm head diameter and a 6.97mm stem, measuring 98.25mm in overall length. The 22-degree seat angle is designed for improved flow.

These valves are constructed from a high-strength, heat-resistant alloy, making them well-suited for demanding engine builds. The Competition Plus series is known for its durability and ability to handle higher cylinder pressures and temperatures often found in modified or performance-oriented engines. The +1mm sizing on these valves means they are slightly larger in diameter than stock, which can help increase airflow and improve performance when used in a properly ported cylinder head.

When rebuilding or modifying your 1FZFE engine, using valves designed for performance can make a notable difference. Ensure your cylinder head is prepared to accept the slightly larger valve size for optimal sealing and performance.
