Product Details

The Supertech Performance VWIVN-1034 is a high-performance, black nitrided stainless steel intake valve engineered for the VW/Audi 2.0L 16V engine platform. Built to standard size specifications, this valve features a 32.00mm head diameter, 6.95mm stem diameter, and an overall length of 95.50mm, making it a precise-fit replacement or upgrade for performance engine builds.

Constructed from a single piece of forged stainless steel (EV8 / 21-4N alloy), the VWIVN-1034 delivers exceptional strength and long-term reliability under demanding operating conditions. Each valve is treated with Supertech's Black Nitride coating—a full-valve hardening process that produces a microhardness of 800HV minimum, a surface finish smoother than chrome-plated stems, and significantly reduced friction between the valve stem and guide. Unlike chrome coatings which are applied only to the stem, Black Nitride is applied to the entire valve for complete protection.

Key Features:

  • Head Diameter: 32.00mm (standard size)
  • Stem Diameter: 6.95mm
  • Overall Length: 95.50mm
  • Material: One-piece forged stainless steel (EV8 / 21-4N alloy)
  • Coating: Full Black Nitride treatment — 800HV minimum microhardness
  • Profile: Undercut stem, backcut head, dish face design for optimized flow
  • Valve Type: Intake
  • Sold: Per valve — order the quantity equal to your engine's intake valve count

The Black Nitride hardening treatment provides a smooth, low-friction surface finish and bonds to the base material at a microscopic level, ensuring it will not flake or fracture under impact. This process makes the VWIVN-1034 an ideal choice for high-revving, naturally aspirated, turbocharged, and supercharged builds where heat and wear resistance are critical.

Note: This valve is sold individually. Determine the number of intake valves your engine requires and order that quantity.

Fast delivery

This is my first experience ordering from Autoplicity. I was searching for tires online and found that tire rack and Big O tires both listed the size/brand that I needed as out of stock. Auto closely said that they had many in stock and at the best prices. I was pleasantly surprised to receive them within 2 to 3 days. I will definitely be ordering from them again in the near future.

Thank you for the good service

Very pleased with the service. Would recommend to others.

Ok so far

Easy to do business with!

It was simple and fast. Thanks.

I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

Prompt shipping, good prices. Will buy from again

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

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

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
