Supertech BMW N54 Sodium Filled Inconel Exhaust Valve - Set of 12 | Multiple BMW Fitments (BMEVI-1054S-HS-12)

BMW N54 Turbo Sodium Filled Exhaust Valves by Supertech

Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines.

A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market
