Product Details

The Supertech Performance HIVN-1001F is a high-performance, black nitrided intake valve engineered for Honda B-series engines. Featuring a +1mm oversize 34.00mm head diameter, 5.48mm stem diameter, and 102.50mm overall length, this flat-face valve is precision-crafted for demanding race and high-performance street applications.

Manufactured from one-piece forged stainless steel alloy and CNC-finished to strict tolerances, the HIVN-1001F delivers exceptional strength, dimensional consistency, and long-term reliability under extreme engine conditions.

Black Nitride Surface Treatment:

  • Minimum surface microhardness of 800HV — harder than the stainless steel base material while maintaining ductility beneath the nitrided layer
  • Smoother surface finish than chrome-coated stems, reducing friction between the valve stem and guide
  • Treatment is applied to the entire valve, not just the stem, for uniform protection
  • Nitrided layer bonds at a microscopic level and will not flake or fracture upon valve-to-piston contact

Valve Specifications:

  • Head Diameter: 34.00mm (+1mm Oversize)
  • Stem Diameter: 5.48mm
  • Overall Length: 102.50mm
  • Face Style: Flat Face
  • Material: Black Nitrided Stainless Steel
  • Valve Type: Intake

Sold individually — order the quantity equal to the number of intake valves required for your engine build.

I select Mazda Miata '94 and it keeps taking me to this Clock Spring, but Miata is not listed in the fitting. If it does not work, I can always return it :)
