Product Details

The Cometic C3413-EST Hi-Performance Top End Gasket Kit is specifically engineered for 2007-2010 KTM 450SX-F motorcycles with a 100mm bore. This comprehensive EST (Extreme Sealing Technology) kit provides everything needed for a professional top-end rebuild, from the cylinder base gasket up to the head gasket.

EST Extreme Sealing Technology:

  • Embossed stainless steel head, base, and rocker gaskets with proprietary rubber coating for superior sealing
  • Multi-Layer Steel (MLS) head gasket construction for maximum durability under extreme temperatures and pressures
  • Advanced materials designed to withstand the high-performance demands of modern lightweight engines
  • Heat dissipation technology draws heat away from the combustion ring to eliminate hot spots and prevent gasket failure

Complete Kit Includes:

  • Head gasket with precise 100mm bore specification
  • Base gasket for proper cylinder-to-case sealing
  • Cylinder O-rings and all top-end specific seals
  • All necessary gaskets, washers, and O-rings for a complete top-end rebuild

Cometic gaskets are proudly manufactured in the USA using materials sourced from American suppliers. Each component is precision-engineered to meet or exceed OEM specifications and is used by professionals in high-performance racing applications worldwide. Designed for maximum seal integrity, flexibility, and torque retention in demanding motocross and off-road conditions.

What I thought would be a nice and easy purchase didn't quite turn out that way. I ordered the Holley fuel pump module for my 1999 Chevy Suburban K1500, because I wanted an upgrade from OEM to take advantage of the mods I have done to my truck. Autoplicity was the only vendor that offered a cost effective shipping upgrade: $60.98 for Next Day Air UPS, plus they showed the item in stock in their warehouse. The next day, I received an email confirming my order, but never reflected the item being shipped. I called customer service later in the day, but was told that the warehouse was already closed and that I could expect a shipping confirmation email the next day, which would have been Thursday. I had originally ordered the pump on Tuesday night and had my truck towed to my garage Wednesday late morning. I had alerted the shop that I had ordered the part and expected it Thursday, so they could install it and get my truck back by close of business Friday. It wasn't until late Thursday morning, when I once again had to call Autoplicity customer service, that I learned that the warehouse had made a mistake and sent the pump UPS Ground with the tracking showing delivery by Friday end of day. I finally received the pump around 1 PM Friday, and was luckily able to deliver it to my shop and have the install done that afternoon. I am giving 4 stars because the end result was that I got my truck back Friday evening, waiting for the Holley pump was the right decision in terms of vehicle performance, and Autoplicity refunded me my $60.98 for expedited shipping. I will consider them in the future for my auto parts needs.
