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, the TEVI-1014 reflects a commitment to continuous improvement — delivering exceptional flow, durability, and precision quality for demanding performance applications.

Supertech recognizes that every engine has unique requirements, which is why their valves are offered in multiple materials to match any build's needs:

Material Options:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and long-term reliability. Supertech primarily uses EV8 (21-4N) alloy for both intake and exhaust valves, with additional alloy options and heat treatment variants available for specific engine applications.
  • Inconel 751 Nickel-Base Alloy: Engineered for exhaust valves operating under extreme heat conditions — ideal for forced-induction applications including turbocharged and supercharged engines where standard materials fall short.

Coating Technologies:

  • Chrome Coating: A widely used surface treatment in performance valves, providing excellent hardness and wear resistance.
  • Black Nitride Coating: A hardening treatment that produces a smoother surface than traditional chrome, resulting in reduced 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).

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

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. Order Number: 9111

Amazing prices and amazing shipping speed! Best all around. Will be ordering more soon!
