Product Details

The Supertech Performance AIVN-1206S is a high-performance intake valve featuring a single groove design. Built on over 20 years of manufacturing expertise, this valve is engineered for maximum flow rate, durability, and reliability in demanding engine applications.

Construction and Materials:

  • One-piece forged stainless steel construction for superior strength
  • Manufactured from EV8 (21-4N) stainless alloy with specialized heat treatment
  • Available with chrome coating or black nitride treatment for enhanced wear resistance
  • Single groove stem design for reliable valve keeper retention

Performance Features:

  • Optimized flow characteristics for improved engine breathing
  • Black nitride coating option provides smoother surface finish than chrome, reducing friction between stem and guide
  • Precision-manufactured to strict tolerances for consistent performance
  • Designed through extensive testing and collaboration with professional engine builders

Supertech offers valves in various materials to meet the specific demands of different engine applications, from naturally aspirated to forced induction builds. Each valve is sold individually, so be sure to order the correct quantity for your complete valve train.

Note: Price is per valve. Determine total valves needed for your application and order accordingly.

Very easy

first time shopping in this web and it's very easy and fast , great .

great prices, love the option to pay via amazon. hope it arrives as quickly as needed!

Product was exactly as described. Rob@Autoplicity was great when I had an issue with packages being stolen from my porch and got it delivered to a secure site. Great company and will order from again when I need parts for my Acura.<br><br>Disclaimer: 5 star rating seems cliche but this was exactly what I hope for in online purchase experiences.

I have to say I was skeptical at first because autoplicity's price beat everyone by so much! Then I estimated my shipping charges with their system and that too was real cheap for this heavy item I ordered! I ordered it on Sunday and it showed up on Tuesday afternoon! So exceptional pricing meets exceptional shipping and my item is the real thing for a lot less leaves me completely satisfied with this company! I will be recommending them to my friends and family, thanks!

Great price. I hope that the hitch extender quality is as good as the shopping experience>

Great price,quick and easy process.

Had a great price on the parts that I wanted, informed me immediately that the products were back ordered from the manufacturer, and wanted to know if I wanted the parts dropped shipped from the manufacturer or what. They said if I wanted to wait it would take around 2 weeks to ship, they arrived in a week.
