Product Details

Supertech Performance brings over 20 years of precision manufacturing experience to their engine valve lineup. Engineered in close collaboration with professional engine builders, Supertech valves are designed to deliver high flow rates, exceptional durability, and consistent quality across a wide range of performance applications.

Supertech recognizes that every engine has unique demands, which is why their valves are available in a variety of materials and finishes. Each valve is a one-piece forged construction for maximum strength and long-term reliability.

Available Materials:

  • Stainless Steel (EV8 / 21-4N Alloy): The primary material used for both intake and exhaust valves. One-piece forged construction ensures superior strength. Additional alloys with specialized heat treatments are also available for application-specific requirements.
  • Inconel 751 Nickel-Base Alloy: Used for exhaust valves in high-heat environments, making it ideal for turbocharged and supercharged applications where exhaust temperatures are extreme.

Coating Options:

  • Chrome Coating: A widely used finish in performance valve applications, providing excellent surface hardness and heat resistance.
  • Black Nitride Coating: A surface-hardening treatment that creates a smoother finish than chrome, resulting in reduced friction between the valve stem and guide for improved longevity and performance.

Sold individually — one valve per unit. When ordering for an engine that requires multiple valves (for example, 16 valves in a 4-cylinder engine), please order the appropriate quantity to match your engine's total valve count.

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

great - thx!

Great deals at unbeatable prices!

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!!!!

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.
