Product Details

The Supertech Performance VWIVN-1029 is a high-performance intake valve engineered for Volkswagen 2.0-liter engines. With a 42mm head diameter (+1mm oversize), 7mm stem diameter, and 98.60mm overall length, this valve is precision-manufactured for superior flow, durability, and reliability in demanding performance applications.

  • Black Nitride Coating — Provides a microhardness of 800HV minimum, exceeding the base stainless steel material while maintaining ductility beneath the hardened layer
  • Smoother Stem Surface — Black nitrided finish produces a smoother surface finish than chrome-coated stems, reducing friction between the valve stem and guide
  • Undercut & Backcut Design — Optimized for improved airflow and high-flow performance
  • Dish Profile — Engineered head geometry for enhanced combustion efficiency
  • +1mm Oversize Head Diameter — Ideal for use with recut or oversized valve seats during engine rebuilds or performance upgrades

Jennifer was very helpful with ALL questions and coupons. Thank you, Mike D.

Great price beats everyone. Just hope it’s what I ordered.

Cheapest price on Walker exhaust even with shipping and I am in the industry

Ordered what I was looking for, it arrived two days later.

quick and easy

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

Great Price!!<br>Fast Shipping!!<br>Would definitely use again....

fast and easy competitive pricing

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.

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.

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.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!
