Supertech Titanium Retainer for Honda D16Z Y Series Spring SPR-1002S

Supertech is known for making performance engine parts, and this titanium retainer is a great example of that focus. It's designed to work with the SPR-1002S valve springs, specifically for Honda D16Z Y Series engines. Using titanium helps keep the valvetrain weight down, which can make a difference in how the engine performs at higher RPMs.

This retainer is a well-built piece that's lighter than stock steel retainers. That reduced mass means less inertia for the valve springs and camshaft to overcome, potentially leading to improved valve control, especially when you're pushing the engine hard. It's a small part, but it plays a role in the overall efficiency and responsiveness of the valvetrain.
