Ferrea Mitsubishi 4B11T +.001 Exhaust Valve Guide - Set of 8 (Use w/VS1024)

Ferrea is well-known for making high-performance engine components, and this set of eight exhaust valve guides for the Mitsubishi 4B11T engine is a prime example. These guides are crucial for ensuring your valves move smoothly and seal properly, which directly impacts engine performance and longevity. If you're rebuilding the top end of your 4B11T, especially if you're looking to optimize airflow and valve action, these guides are a solid choice.

This particular set is sized at +.001, meaning they are slightly larger than stock to accommodate specific engine builds or to ensure a precise fit after machining. They are designed to be used with Ferrea's VS1024 valve springs, suggesting a coordinated approach to valve train assembly. Proper valve guide installation is key to preventing valve stem wear and maintaining consistent compression.
