Product Details

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup, working directly with professional engine builders to deliver precision components that meet the demands of high-performance and race applications. The VWEVN-1029 is engineered for exceptional flow rates, long-term durability, and consistent quality.

Construction & Materials:

  • One-Piece Forged Stainless Steel — Supertech primarily uses EV8 (21-4N) alloy for both intake and exhaust valves, offering superior strength and reliability over multi-piece designs. Additional alloys with specialized heat treatments are available for specific applications.
  • Inconel 751 Nickel Base Alloy — Used for exhaust valves in extreme-heat environments, including turbocharged and supercharged applications where standard stainless steel alloys may not suffice.

Coating Options:

  • Chrome Coating — A widely used treatment in performance valves, providing enhanced surface hardness and wear resistance.
  • Black Nitride Coating — A hardening treatment that delivers a smoother surface finish compared to 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 engine build. For example, a 16-valve engine requires a quantity of 16.

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.
