Product Details

The Supertech Performance TIVN-1035 is a high-performance stainless steel intake valve finished with a Black Nitride coating, engineered for demanding race and street performance engine builds. Manufactured from a single piece of forged EV8 (21-4N) stainless steel, this intake valve delivers exceptional strength, durability, and high-flow performance over standard OEM valves.

Key Features:

  • One-Piece Forged EV8 (21-4N) Stainless Steel Construction — Single-piece forging eliminates weak points and ensures maximum structural integrity under high-RPM and high-temperature conditions
  • Black Nitride Coating — Applied to the entire valve (not just the stem), this hardening treatment achieves a minimum surface microhardness of 800HV while delivering a smoother finish than chrome-coated valves, reducing friction between the valve stem and guide for longer service life
  • Multi-Stage Heat Treatment — Each valve undergoes a specialized heat treatment process calibrated to the specific engine application, ensuring the correct hardness profile and durability
  • Precision CNC Machined — Machined to tight tolerances for consistent dimensions, optimized valve angles, and improved airflow through the cylinder head port
  • High-Flow Design — Engineered to maximize intake airflow and improve cylinder head efficiency, making these valves ideal for naturally aspirated, turbocharged, and supercharged builds
  • Sold Individually (Per Valve) — Order the exact quantity required for your engine (e.g., order 16 for a 16-valve engine)

Supertech Performance brings decades of racing valve manufacturing expertise to every product. The TIVN-1035 intake valve is built to withstand the rigors of high-output performance engines, providing a reliable, long-lasting upgrade over factory valves in race and street applications alike.

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....

Easy to use website.

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!!!!
