Uprated Valve Stem Seals – EA888 Gen 3 Engine

If you own an EA888 Gen 3 engine, you’ve probably heard of (or experienced) valve stem seal failure — sometimes in as little as 40,000 miles.

Our UNA Performance Uprated Valve Stem Seals are the proven fix.

Used in every one of our in-house builds, these seals eliminate the common oil consumption issues and premature wear found with OEM seals.

Manufactured from high-temperature, oil-resistant materials, these are built to withstand the higher cylinder temps and boost levels found in tuned or hard-driven engines.

✅ Direct fit replacement for EA888 Gen 3 engines

✅ Resistant to heat and oil breakdown

✅ Proven in multiple high-performance UNA builds

✅ Perfect upgrade during head rebuilds or full engine builds

Engineered for long-term reliability — not just another replacement part.
