Product Details

Supertech Performance brings over 20 years of manufacturing expertise to their precision-engineered engine valves. Developed through intensive testing and close collaboration with professional engine builders, each valve delivers exceptional flow rates, long-term durability, and consistent quality across a wide range of performance applications.

Material Options:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and reliability. Supertech primarily uses EV8 (21-4N) alloy for both intake and exhaust valves, with additional alloy and heat treatment options available for specific engine requirements.
  • Inconel 751 Nickel-Base Alloy: Designed for exhaust valves operating under extreme heat conditions, including turbocharged and supercharged applications where standard materials may not suffice.

Coating Technologies:

  • Chrome Coating: A widely-used surface treatment for performance valves, providing enhanced hardness and wear resistance.
  • Black Nitride Coating: A thermochemical hardening treatment that produces a smoother surface finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Important Ordering Note: Supertech valves are sold individually (per valve). Please order the exact quantity required for your application — for example, a 16-valve engine requires a quantity of 16.

My husband found the part we needed for an older model vehicle and it was reasonably priced. The item was shipped in a very timely manner and we will definitely consider ordering from here again.

Great quick

I couldn't find the part anywhere, without having to send in my distributor to be rebuilt. You guys came through huge having it in stock and delivering it within only a few days. Thanks!!

Say what you do and do what you say.

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....

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, fast shipping.

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.
