About Cometic

Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.

Ensure a perfect seal for your Twin Cam intake manifold with this 10-pack of Cometic Carb/EFI gaskets. These OEM-replacement gaskets are purpose-built to prevent air leaks at the intake interface on both carbureted and fuel-injected V-twin engines.

Why riders pick this

  • OEM-spec replacement for Twin Cam intake
  • Compatible with both carb and EFI Twin Cams
  • Prevents intake air leaks for optimal performance
  • Durable construction for V-twin engines
  • Economical 10-pack for shops and enthusiasts

Maintaining an airtight seal at the intake manifold is crucial for proper engine performance, especially on a V-twin. These Cometic Twin Cam Carb/EFI gaskets are engineered to meet or exceed OEM specifications, providing a direct replacement for your factory units. The 10-pack quantity is a smart choice for professional shops, service departments, or riders who frequently work on their bikes and need to keep spares readily available.

Reliable Intake Sealing

  • Direct OEM replacement for Twin Cam carb and EFI applications
  • Engineered to prevent air leaks at the intake manifold interface
  • Designed for durability under V-twin engine conditions
  • Bulk 10-pack for shop use or multi-bike owners

Crucial for Engine Performance

An intake leak can lead to a lean condition, rough idle, and poor throttle response on your Twin Cam. Replacing old, hardened gaskets with fresh Cometic units is a simple yet critical step in maintaining optimal engine tune and reliability. Whether you're installing a new air cleaner, upgrading your intake, or just performing routine maintenance, these gaskets provide the peace of mind that your intake system is sealed tight.

Works Fine at a lower cost

I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.

A mediocre gasket

I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
