Product Details

Supertech Performance SIVN-1010 valves are engineered with over 20 years of manufacturing expertise to deliver exceptional flow rates, durability, and precision for high-performance engines. Each valve is designed through extensive testing and collaboration with professional engine builders to ensure optimal performance across demanding applications.

Material Options and Construction:

  • Stainless Steel: One-piece forged construction using primarily EV8 (21-4N) alloy for both intake and exhaust applications, with specialized alloys and heat treatments available for specific engine requirements
  • Inconel 751: Nickel-base alloy designed for extreme-temperature exhaust applications including turbocharged and supercharged engines

Advanced Coating Options:

  • Chrome Coating: Proven performance coating widely used in racing and high-performance applications
  • Black Nitride: Advanced hardening treatment that creates a smoother surface than chrome, reducing friction between the valve stem and guide for improved longevity

The one-piece forged design provides superior strength and reliability compared to multi-piece valves, while the range of materials and coatings allows builders to select the optimal valve specification for each unique engine build.

Note: Supertech valves are sold individually. Order the total quantity needed for your application (example: order quantity 16 for an engine requiring 16 valves).

I didn't see an estimated ship/arrival time

easy to purchase.

Great

My experience with Autoplicity was great, I couldn't have asked for better service. It's not everyday you order something online and it shows up two days sooner than first expected.

easy and painless

Quick delivery good parts

It was simple and fast. Thanks.

Easy. Best price anywhere.

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.

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!!!!

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. Order Number: 9111

This store had a lot of products more than most other sites I looked at. The order was processed quickley and shiped the next day. I will use them again.
