Product Details

The Cometic C3171-EST Top End Gasket Kit provides complete top-end sealing for 68mm bore Honda engines using Cometic's advanced Extreme Sealing Technology (EST). This comprehensive kit includes everything needed to rebuild the top end from the cylinder base upward.

Extreme Sealing Technology (EST):

  • Embossed stainless steel head, base, and rocker gaskets covered with proprietary rubber material
  • Advanced head gasket material draws heat away from the combustion ring and dissipates it evenly across the gasket surface
  • Eliminates hot spots and prevents gasket failure under extreme conditions
  • Superior sealing performance compared to conventional composite gaskets

Complete Top End Kit Includes:

  • Head gasket designed for 68mm cylinder bore
  • Base gasket for cylinder-to-crankcase sealing
  • Rocker cover gasket
  • All necessary O-rings and seals for complete top-end rebuild

Engineered specifically for Honda applications, this kit delivers OEM-quality fitment with performance-grade materials trusted by professional engine builders and enthusiasts worldwide.

Great experience.

So far, so good. More after receipt of product and installation. As it turned out, I ordered the wrong window kit, which is completely my fault, so I will have to pay return shipping and there will be a restock fee. Customer service dealt with my issue

easy and efficient

Great customer service, received tracking number quickly.

Your site looks professionally constructed and has an easy to understand interface.

Your site is great Awesome selection and great items. Thanks for free shipping!!

Ordered a Thule Bike Rack from Autoplicity and was greatly pleased with the price. It was the best on the internet. There was an issue with the shipment of the item and some confusion but this was resolved in a professional manner by a customer service manager. Overall, I'm pleased I got a deal.

I liked the website and it's layout. Very easy to find merchandise. When I called i liked the fact that I was put through to a person right away.

Fast

I ordered the Edge Evolution CS for my 2008 F150 and it has brought my truck to life. Setup was simple and I could immediately feel the difference in the acceleration and transmission shifting. I would definitely recommend this product.<br>Autoplicity had the best price on the tuner that I could find for brand new. However, they did charge for shipping and it was slower than other sites I looked at. Overall, I still got the tuner cheaper that any other competitor.

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.

Fast shipping! Good prices! Will recommend to others
