Product Details

Supertech Performance brings over 20 years of manufacturing expertise to the PEEVN-28606 engine valve. Developed through intensive testing and close collaboration with professional engine builders, this valve delivers the high flow rate, durability, and precision quality demanded by performance and racing applications.

Supertech recognizes that every engine has unique requirements, which is why their valves are available in a range of premium materials to match any build:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. Supertech primarily uses EV8 (21-4N) stainless for both intake and exhaust valves, with additional alloys and specialized heat treatments available for specific applications.
  • Inconel 751 Nickel-Base Alloy: Used for exhaust valves in extreme high-temperature environments, including turbocharged and supercharged applications where standard stainless steel reaches its thermal limits.

To combat heat and wear, Supertech applies two industry-proven surface treatments:

  • Chrome Coating: A widely used finish in performance valves, providing excellent hardness and corrosion resistance.
  • Black Nitride Treatment: A hardening process that produces a smoother surface finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Sold individually (per valve). Order the quantity equal to the total number of valves required for your engine build — 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.

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.

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!!!!

They carried the parts i was looking for at an amazingly discounted price. I'm not dissapointed even though the initial ship took 5 days to begin. Per their note they do inform the customer of 1 day to process the order and another 3 "business days" to SHIP. Seems like in this age of instantaneous communications the lag should be dramatically less. Generally, a more robust processing center can ship same day if in the same time zone and order arrives before 2pm - a goal to shoot for! ;)
