Product Details

The Supertech Performance NEVI-1042-SL is a precision-engineered performance valve designed specifically for Nissan RB20DE and RB20DET engines, commonly found in Skyline models. Manufactured with over 20 years of valve production expertise, this high-performance valve delivers improved flow rates, enhanced durability, and exceptional quality for both street and racing applications.

Construction and Materials:

  • One-piece forged stainless steel design for maximum strength and reliability
  • Manufactured from premium EV8 (21-4N) alloy with application-specific heat treatment
  • Available with advanced surface coatings including chrome or black nitride for reduced friction and improved wear resistance
  • Black nitride coating provides a harder, smoother surface than traditional chrome, reducing friction between valve stem and guide

Performance Benefits:

  • Optimized flow characteristics for improved engine breathing and power output
  • Superior heat resistance for turbo and high-performance applications
  • Precise tolerances ensure proper valve train operation and longevity
  • Designed and tested in collaboration with professional engine builders

Application: Compatible with Nissan RB20DE and RB20DET engines as found in Skyline models. This valve is sold individually—ensure you order the correct quantity for your complete valve train rebuild (typically 8, 12, or 16 valves depending on engine configuration).

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

So far so good. First timer with this seller.

Great deals at unbeatable prices!

So far so good

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.

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!!!!
