Product Details

The Supertech Performance PEEVN-28705 is a standard size (+0.00mm) Inconel exhaust valve featuring a black nitride coating, engineered for the Peugeot/Citroën 2.0L 16V EW10J4S engine. With a 31mm head diameter, 5.95mm stem diameter, and 102.85mm overall length, this valve is a precision-machined, direct-fit replacement built to exceed OEM performance standards.

Supertech combines over 30 years of motorsport manufacturing experience with cutting-edge metallurgy to produce valves trusted by professional engine builders worldwide. This exhaust valve is manufactured from Inconel 751, a nickel-based superalloy engineered to withstand the extreme exhaust gas temperatures produced in performance, turbocharged, and supercharged applications.

Key Features:

  • Inconel 751 Nickel-Base Alloy — Provides superior heat resistance and reliability under extreme exhaust temperatures, ideal for forced-induction and high-performance builds
  • Black Nitride Surface Treatment — Creates a harder surface finish compared to chrome, reducing friction between the valve stem and guide for improved longevity and reduced power loss
  • Standard Size (+0.00mm) — Direct drop-in fitment with no cylinder head machining required
  • Head Diameter: 31.00mm
  • Stem Diameter: 5.95mm
  • Overall Length: 102.85mm
  • One-piece forged construction for maximum strength and structural integrity

Sold individually (per valve). Order the correct quantity to match your engine's total exhaust valve count — the EW10J4S 16V engine uses 8 exhaust valves.

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.

Easy to find what I was looking for, and checking out with Amazon worked great.

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!!!!

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.
