Stem diameter: 9.5 mm (0.374 inches)
Overall length: 122.8-122.9 mm (4.835-4.839 inches)
Seat angle: 45° precision-ground sealing face
Stem type: Single-groove for split collet retention (7° collet angle)
Tip configuration: Induction-hardened to resist wear from rocker arm contact
Weight: 0.14 kg (140 grams) per valve
Quantity per engine: 4 pieces for 1004.4 series (4-cylinder), 6 pieces for 1006.6 series (6-cylinder)
Material & performance features:
Manufactured from high-alloy heat-resistant steel containing 0.35-0.45% carbon, 1.5-2.5% chromium, with additions of manganese and silicon for enhanced high-temperature strength and wear resistance . The valve head undergoes solution treatment at 1,050-1,100°C followed by age-hardening to achieve 25-30 HRC hardness, maintaining structural integrity at intake air temperatures up to 200°C in turbocharged applications.The stem receives gas nitriding treatment creating a 0.02-0.04 mm deep surface layer exceeding 700 HV hardness to resist scuffing during prolonged operation. The 45° seat angle is precision-machined to Ra 0.4-0.8 µm finish, ensuring positive sealing with the valve seat insert and preventing intake air leakage and compression loss. The tip is induction-hardened to 50-55 HRC to resist cupping under 800-1,000 N valve spring loads .
