Supertech VW/Audi 1.8T Sodium Filled Inconel Exhaust Valve - +1mm Oversize - Set of 8 | Multiple Audi/Volkswagen Fitments (AEVI-1106S-HS-8)

Audi 1.8T 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
