Product Details

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup. Developed through intensive testing and close collaboration with professional engine builders, Supertech valves are engineered for high flow rate, 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 multiple materials and finishes to match any build requirement.

Available Materials:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. Primarily used for both intake and exhaust valves, with additional alloy options and heat treatment variants available for specific applications.
  • Inconel 751 Nickel-Base Alloy: Designed for exhaust valves operating at extreme temperatures, making this material ideal for turbocharged and supercharged engine builds where heat management is critical.

Coating Options:

  • Chrome Coating: A widely used finish in performance valve applications, providing a hard, wear-resistant surface.
  • Black Nitride Treatment: A surface-hardening process that produces a smoother finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Sold individually — one valve per unit. Please order the exact quantity required for your engine build (e.g., order 16 for a 16-valve engine).

Being on disability with spinal injury I like the ease of ordering.

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

found what I need at the price I want to pay. there is not a lot of details on what you are buying. I found I had to check with other sites to insure I was buying what I wanted. also postponed buying brakes becuase of this.

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.

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.
