Product Details

The Supertech Performance HIVN-1020D is a precision-engineered black nitrided intake valve designed for Honda and Acura K-Series engines. Featuring a 35.00mm standard head diameter, 5.48mm stem diameter, and 108.85mm overall length, this valve is manufactured to exacting tolerances for reliable high-performance and competition use.

Key Features:

  • Black Nitride Treatment: Applied to the entire valve surface — not just the stem — for superior hardness and a smoother finish than chrome-coated alternatives, reducing friction between the stem and guide at high RPM
  • Bonded at a Microscopic Level: The nitrided layer adheres to the base material so it will not flake or crack even under valve-to-piston impact conditions
  • One-Piece Forged Stainless Steel Construction: Forged from high-strength stainless steel alloy (EV8 / 21-4N) for exceptional durability and heat resistance
  • Dished Head Profile: Optimized head geometry for improved flow characteristics in K-Series applications
  • Specifications:
    • Head Diameter: 35.00mm (standard)
    • Stem Diameter: 5.48mm
    • Length: 108.85mm
    • Material: Black Nitrided Stainless Steel
    • Valve Type: Intake

Supertech Performance draws on over 20 years of valvetrain manufacturing experience, working directly with professional engine builders to continuously refine their product line. The HIVN-1020D delivers the high flow rates, tight tolerances, and long-term durability demanded by performance and race engines.

Great deals at unbeatable prices!

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

Best Price, Fast shipping, couldn't ask for anything more.

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

Great
