Product Details

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

Material Options:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. Supertech primarily uses EV8 (21-4N) steel for both intake and exhaust valves, with additional alloy grades and heat treatments available for specialized applications.
  • Inconel 751 Nickel-Base Alloy: Used for exhaust valves in extreme-heat environments, including turbocharged and supercharged engines where standard materials may fail under sustained elevated temperatures.

Protective Coating Options:

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

Sold individually — one valve per unit. Please order the exact quantity required for your application. For example, a 16-valve engine requires a quantity of 16.

I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

Found item i was looking for at a better price than any other website! Fast shipping and great custumer service. will be buying from them again. Thanks!

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

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.

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.
