Supertech Inconel Exhaust Valve - Single | Multiple Honda/Acura Fitments (HEVI-3228)

Honda J30/J32 Inconel Exhaust Valve 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
