Supertech Exhaust Valves (Set of 8) – VW/Audi MQB 1.8T/2.0T

Supertech Exhaust Valves for VW/Audi EA888.3 Supertech manufactures a variety of high performance Inconel valves for many applications. These valves are manufactured from a Nickel base super alloy material (Inconel 751 or Nimonic 80A) this material is chosen because it is designed to withstand very high temperatures. These valves feature a one-piece forging, hardened tip, and our “superfinish” stem. Our Inconel valves are extremely popular choice for turbo and supercharged applications. 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 VWEVI-1002S Head Diam: 28.00mm (STD) Stem Diam: 5.96mm Length: 101.80mm Material: Inconel Groove Type: Single Groove Valve Type: Exhaust Keepers: KPR-6S/7 (Included) VWEVI-1004S Head Diam: 29.00mm ( 1mm) Stem Diam: 5.96mm Length: 101.80mm Material: Inconel Groove Type: Single Groove Valve Type: Exhaust Keepers: KPR-6S/7 (Included) VWEVI-1006S Head Diam: 30.00mm ( 2mm) Stem Diam: 5.96mm Length: 101.80mm Material: Inconel Groove Type: Single Groove Valve Type: Exhaust Keepers: KPR-6S/7 (Included)
