This gasket features an 86mm bore diameter and a compressed thickness of .092 inches (2.34mm), making it ideal for stock and performance engine builds.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and sealing performance
  • 86mm bore diameter optimized for RB25 engine applications

  • Engineered for both naturally aspirated RB25DE and turbocharged RB25DET engines
  • High-temperature resistant design withstands extreme cylinder pressure and heat

Great pricing!! cheapest products on the web!

Your competitive pricing won my business through the internet and I wasn't disappointed. The price was great ( about 1/2 MSRP) and item was shipped very quickly. No backorder problems here! I was impressed with the quality of my H pipe and with the packaging.

The company shipped fast and was easy to communicate with. Would recommend this company.

I really like how prompt the order went through and the quality of the part im getting

Best price for a product I've been shopping for, for months, and when I saw Autoplicity having it for A LOT cheaper, putting the product in my sweet spot price wise, I didn't hesitate to order. <br><br>My bank was a little slow to post the transaction, and I was suprised to get a human on the phone with no effort to make sure my order was properly processed. The gentleman I spoke with was very friendly and promptly answered all my questions. <br><br>Only the $5 I'm getting back for this review can make this deal any better, as I have no suggestion for improving the transaction I made with them.

Great place to shop online. The best price on the internet and super fast delivery. Shop with Autoplicity, highly recommended.

Autoplicity leads the way ! Others take a lesson !! Great prices and excellent service !!!

Autoplicity had the best price for my Thule 867 roof rack cargo bag. It was easy to pay thru my Amazon accont and the order shipped within 24 hours of my placing the order.

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT

Fast shipping and good prices. I would shop this site again.
