Supertech Toyota Supra (A90)/BMW B58B Sodium Filled Inconel Exhaust Valve - Single (Drop Ship Only)

Supertech is known for making well-built valvetrain components, and this sodium-filled Inconel exhaust valve is a prime example. If you're working on a Toyota Supra (A90) or a BMW with the B58B engine, this valve is designed to handle the intense heat found in performance applications.

The key here is the Inconel material, which is a superalloy that holds up much better to high temperatures than standard stainless steel. Combined with the sodium filling, which acts like a heat exchanger inside the valve stem, this setup significantly improves heat dissipation away from the valve face. This helps prevent premature wear and potential failure under demanding conditions, keeping your engine running strong.

This is a single exhaust valve, so make sure you order the correct quantity for your engine rebuild or repair. It's a direct replacement part for the exhaust valve position.
