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

If you're rebuilding the top end of your Toyota 1FZFE engine for serious performance, you'll want to pay close attention to the valves. These Ferrea exhaust valves are specifically made for the 1FZFE, featuring a 33mm head diameter and a +1mm oversized stem for improved flow and sealing. The 22-degree seat angle is a common performance modification that helps improve gas flow out of the cylinder.

Ferrea uses a special super alloy for these valves, which is crucial for handling the higher temperatures and pressures found in modified or performance-oriented engines. This material is well-built to resist wear and deformation, even under demanding conditions. The valves measure 98.25mm in overall length, and the +1mm stem size means you'll need to ensure your valve guides are reamed or honed to accommodate them, a standard procedure for performance engine builds. This set includes all 12 exhaust valves needed for a complete engine rebuild.

When building a high-performance 1FZFE, using valves designed for the stresses involved is essential for reliability and power. These Ferrea valves are a solid option for anyone looking to get the most out of their engine rebuild.
