Product Details

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

Supertech recognizes that every engine has unique demands, which is why their valves are available in multiple materials and finishes to suit any build — from street performance to fully built forced induction motors.

Available Materials:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. EV8 stainless is Supertech's primary alloy for both intake and exhaust valves, with additional alloys and heat treatments available for specialized applications.
  • Inconel 751 Nickel-Base Alloy: Designed specifically for exhaust valves subjected to extreme heat, making it the ideal choice for turbocharged and supercharged engine builds where conventional stainless alloys may fall short.

Protective Coatings:

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

Sold individually — per valve. 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.

check out was fast and easy

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

The selection is bountiful and the prices beat all I've seen.

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.
