What is the benefit of using a titanium retainer?

Titanium retainers are significantly lighter than steel ones. This reduced mass in the valvetrain can lead to improved engine response and allow the engine to rev more freely, especially in performance builds.

How many retainers do I need to order?

This retainer is sold individually. You will need to order one retainer for each valve in your cylinder head. For a typical 4-cylinder engine, this would mean ordering multiple units.

What does the '7 Deg Pro CNC' designation mean?

This refers to the specific 7-degree angle of the valve lock groove, which is critical for proper valve seating and operation in compatible K20 cylinder heads. The 'Pro CNC' indicates it's a professional-grade part machined using Computer Numerical Control for high accuracy.

About this part

Product Details

Precision CNC machined from titanium, this Ferrea retainer is designed for Acura and Honda K20 engines using a double spring setup with a 7-degree valve angle. Titanium is chosen here because it's significantly lighter than steel, which helps reduce the overall mass that the valve train has to move. This can lead to improved engine response and allow the engine to rev more freely, especially in high-performance applications where every bit of weight savings counts.

This retainer is a single piece, meaning it's sold individually. If you're rebuilding or upgrading your K20 cylinder head, you'll need to order one for each valve. The 7-degree angle is specific to certain K20 valve setups, so make sure this matches your existing or planned configuration. Ferrea is known for making well-built valvetrain components, and this retainer is no exception, offering a solid option for those looking to optimize their engine's performance.
