M20 Performance Dual Valve Spring Set

Your performance camshaft is only as good as the springs behind it.

The BimmerHeads M20 performance dual valve spring set — built to handle the demands of a performance camshaft — the upgrade your M20 cylinder head rebuild deserves.

• No additional hardware required
• Complete set of 12 inner and 12 outer valve springs
• Includes 12 VSIs (valve spring inserts) — everything needed for proper spring seating
