Description
Sodium filled valves are made of a superior Nickel based alloy (Inconel 751). Specifically choose this material because this alloy offers a significant reduction in valve head temperatures. A cooler valve improves the material strength and increases the 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. Our sodium filled valves are a great choice for today’s modern turbo engines., A must for turbos. High Performance Exhaust Valve for 1.8T, 2.7t,2.8L & 3.0L 30v V6 (1mm oversize 30.9mm, 6mm stem). Single groove for ultra high rpm street & race use. Single groove keepers included
