Product Details

The Supertech Performance HIVN-1000 is a Black Nitrided performance intake valve engineered for high-output Honda B-Series engines. With a 33.00mm standard head diameter, 5.48mm stem diameter, and 102.5mm overall length, this valve is precision-manufactured to deliver exceptional flow, durability, and reliability in demanding street and race applications.

Construction & Material:

  • One-piece forged stainless steel construction using high-nickel, high-temperature alloy for maximum strength and reliability
  • Black Nitride treatment applied to the entire valve — not just the stem — for superior surface hardness (minimum 800HV microhardness)
  • Nitrided layer bonds at a microscopic level, preventing flaking or cracking even under valve-to-piston impact conditions
  • CNC-finished to strict tolerances for consistent, race-ready fitment
  • Swirl polished with stem undercut and hardened tip for optimized airflow and longevity

Black Nitride Coating Advantages:

  • Smoother stem surface finish than chrome-coated valves, reducing friction between stem and guide
  • Harder valve seat surface extends service life when used with lead-free fuels, alcohol blends, nitrous, or other aggressive fuel mixtures
  • Compatible with all seat materials including nodular iron, steel powder metal, hard aluminum-copper, and beryllium copper seats
  • Reduced valve-guide friction lowers parasitic power loss at high RPM

Specifications:

  • Head Diameter: 33.00mm (standard)
  • Stem Diameter: 5.48mm
  • Length: 102.5mm
  • Valve Type: Intake
  • Finish: Black Nitrided

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

Ordered the PUTCO RED Blade LED Light Bar PN 92010-60 for my 2018 Ford Raptor w/802A. Package came via FedEx with no damage, packaged well. Installation instructions were in the package but they were not the most current that covers install on 2015-Current Ford F150 and 2017-Current Ford Super-Duty Trucks. The updated instructions can be found here: https://www.putco.com/blade-led-light-bar-60 click on "Product Downloads" below the pictures and select "Installation instructions - For FORD Trucks equipped with BLIS (Blind Spot Information System)". Install took about 4 hours, hardware for tapping into the large white wire on the trailer connector is not provided, you will need a Posi-Tap connector (blue or yellow) - https://www.amazon.com/Lockitt-POSI-TAP-Assortment-connectors-10-22/dp/B00CMC5DII/ref=sr_1_1?ie=UTF8&qid=1543947231&sr=8-1&keywords=posi+tap+connector
