Ferrea Ford Ecoboost 3.5L Exh & Int Valve Guide - Set of 12 (Use w/SL1155)

These Ferrea valve guides are made from a high-grade iron alloy, chosen for its durability and ability to handle the heat cycles common in Ford Ecoboost 3.5L engines. This set includes 12 guides, enough for a full engine rebuild, and is specifically designed to work with Ferrea's SL1155 valve seals. Proper valve guide function is critical for maintaining valve sealing and preventing oil from entering the combustion chamber, which helps keep your engine running smoothly and efficiently.

When you're rebuilding the top end of your Ecoboost 3.5L, ensuring the valves move freely and are properly seated is key. These guides are manufactured to precise tolerances, which helps reduce valve stem wear and ensures consistent performance over time. They are a well-built replacement part for your engine's valve train.
