IAG Beehive Valve Spring and Titanium Retainer Set for Subaru EJ Engine

This is the more serious EJ spring and retainer setup for builds that need better high-rpm control and a little more headroom than a basic single spring package.

• Valvetrain: Beehive spring design with titanium retainers
• Best fit: A better answer for higher rpm combinations and more aggressive cam or boost setups
• Build style: Good choice when the engine is clearly moving out of mild street territory

Fitment: Subaru EJ engines

Why you'd choose it: Choose this when you want more valvetrain control and more confidence at rpm than the entry-level spring package gives you.
