Product Details

The Supertech Performance MAEVN-2301D is a Black Nitrided stainless steel exhaust valve designed for the Mazda and Ford Duratec 2.0L and 2.3L engines. Manufactured from high-grade 23-8N (EV8) stainless steel and featuring a Black Nitride surface treatment, this valve delivers superior wear resistance, reduced friction, and extended service life — making it an ideal upgrade for street performance and moderate-boost applications.

Key Features:

  • Material: Stainless Steel 23-8N (EV8) for high-temperature strength and durability
  • Black Nitride Coating: Hardens the surface, reduces friction, and significantly extends valve life compared to chrome-coated alternatives
  • Head Diameter: 30.00mm (Standard size) — Dish face profile
  • Overall Length: 103.40mm
  • Groove Type: Single groove
  • Stem Superfinish: Precision superfinished stem surface for tighter dimensional tolerances and reduced guide wear
  • Valve Tip: Hardened beyond 52 HRc for long-lasting durability
  • Sold individually

Important Note: When used in Mazdaspeed 3 or Mazdaspeed 6 applications, these valves are compatible only when paired with upgraded Supertech valve guides and seals. If retaining factory guides and seals, use part number MAEVI-2301D-6MM instead.

Supertech Performance, headquartered in San Jose, California, brings over 30 years of motorsport valve engineering experience to every component they produce. Each valve is developed using advanced testing methods including ultrasonic inspection, X-ray analysis, laser measurement, and computerized Finite Element Analysis (FEA) to ensure race-proven reliability in street, drag, rally, and road racing applications.
