Product Details

Supertech Performance brings over 20 years of manufacturing expertise to the MAIVN-2301F engine valve, engineered for high-flow performance, long-term durability, and precision quality. Developed in close collaboration with professional engine builders, each Supertech valve undergoes intensive testing to deliver consistent improvements and reliable results across a wide range of applications.

Supertech recognizes that every engine has unique requirements, which is why their valves are offered in multiple materials and surface treatment options to suit naturally aspirated, turbocharged, and supercharged builds alike.

Available Materials:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. Supertech primarily uses EV8 (21-4N) stainless alloy for both intake and exhaust valves, with additional alloy options and heat treatments available for specialized applications.
  • Inconel 751 Nickel-Base Alloy: Designed for exhaust valves operating under extreme heat conditions, such as those found in forced induction (turbocharged or supercharged) engines where elevated exhaust temperatures are a constant concern.

Surface Treatment Options:

  • Chrome Coating: A widely used surface treatment in high-performance valves, providing a hard, protective layer that resists wear and corrosion.
  • Black Nitride Treatment: A precision hardening process that produces a smoother surface finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Important: 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.

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.

Thanks

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.

The ordering process went really smoothly. Got my ordering info e-mailed smartly and was able to track the order easily. Looking forward to using my item as soon as it gets here!

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.
