What is the main benefit of using titanium retainers?

Titanium retainers are much lighter than stock steel retainers. This reduced weight helps the valvetrain respond more quickly, especially at higher engine speeds, which can improve overall engine performance.

Are these retainers a direct replacement for all Subaru EJ20 engines?

These retainers are specifically designed for Subaru EJ20 engines and feature a 6-degree angle. It's important to verify that this angle matches your specific valve seat configuration and engine build for optimal performance.

What does CNC machining mean for these retainers?

CNC machining ensures that each retainer is manufactured to exact specifications with high precision. This results in a consistent fit and reliable performance across all 16 pieces in the set.
