What is the main benefit of using titanium retainers?

Titanium retainers are significantly lighter than their steel counterparts. This reduced mass in the valvetrain helps improve valve control, especially at higher engine speeds, and can contribute to overall engine reliability under stress.

How many retainers are included in this set?

This set comes with 16 valve spring retainers, which is the standard amount needed for a complete engine in a Mini Cooper S.

Are these retainers suitable for a stock engine?

While these retainers are an upgrade, they are particularly beneficial for engines that have been modified for higher performance or are undergoing a rebuild. They are designed to handle increased stress and RPMs beyond stock specifications.

About this part

Product Details

Crafted from aerospace-grade titanium, these retainers are a notable upgrade for your Mini Cooper S engine. They are designed to handle the increased stress and higher RPMs that come with performance modifications or a rebuilt top end. Titanium is significantly lighter than steel, which helps reduce overall valvetrain mass, allowing for better valve control at high engine speeds.

This set includes 16 retainers, enough for a complete engine rebuild. Ferrea is known for making well-built valvetrain components, and these retainers are no exception. Their precise machining ensures they seat properly on the valve stem, contributing to a stable valvetrain. If you're pushing your Mini Cooper S engine beyond its stock limits, these titanium retainers are a solid choice for improved reliability and performance.
