Product Details

The Supertech Performance PEIVN-28594 is a Black Nitrided Intake Valve engineered for the PSA EW10J4 engine platform. Manufactured from high-grade EV8 (21-4N) stainless steel and finished with a Black Nitride surface treatment, this valve delivers increased hardness, a smoother stem finish, and reduced friction between the valve stem and guide — resulting in longer service life compared to standard chrome-finished valves.

Key Specifications:

  • Part Number: PEIVN-28594
  • Valve Type: Intake
  • Head Diameter: 28.75mm
  • Overall Length: 104.40mm
  • Material: Stainless Steel 21-4N (EV8)
  • Finish: Black Nitride Coating
  • Sold: Individually (Per Valve)

Key Features:

  • EV8 (21-4N) Stainless Steel Construction — One-piece forged design provides superior strength and fatigue resistance for high-performance and forced-induction applications
  • Black Nitride Coating — A hardening surface treatment that produces a smoother finish than chrome, reducing friction between the valve stem and guide and extending valve life
  • Precision Machined — CNC-machined geometry optimizes airflow and ensures a precise fit in the cylinder head
  • Drop-In Fitment — Engineered as a direct replacement for the PSA EW10J4 engine

These valves are sold individually. Order the exact quantity required for your engine build — for example, if your engine requires 8 intake valves, order a quantity of 8.

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

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.

they had the lowest price around for my car's k&n air filter. A great product at wholesale prices!

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.

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.
