Cometic Gasket — Canada
Priced in CAD • No duties • No brokerage fees • Fast shipping across Canada
Cometic Gasket is an Ohio-based manufacturer producing MLS (Multi-Layer Steel) head gaskets, complete gasket kits, and engine sealing products for performance, racing, and OEM replacement applications. Their MLS head gaskets are the industry standard for high-performance and forced-induction engine builds — multiple layers of embossed stainless steel provide superior sealing under the elevated cylinder pressures that stock composite gaskets can't reliably contain. At MyPartsGuy.ca we carry the Cometic lineup, all priced in Canadian dollars with no import fees or brokerage charges.
For any Canadian engine build involving increased boost, elevated compression, or a fresh engine rebuild, Cometic MLS head gaskets are the professional recommendation — they're what engine builders use when a job needs to be done right the first time.

Frequently Asked Questions
Why do I need an MLS head gasket for a boosted engine?
Stock composite head gaskets are designed for factory cylinder pressures. When boost levels increase — particularly on Subaru EJ engines notorious for head gasket failures even at stock power — the additional cylinder pressure can overwhelm a composite gasket's sealing ability. MLS gaskets use multiple layers of embossed stainless steel that conform to surface irregularities and maintain a seal under elevated pressures. Paired with ARP head studs, an MLS gasket is the correct solution for any boosted build.
What bore size do I need for my Subaru EJ25?
Cometic produces EJ25 MLS gaskets in multiple bore sizes — 99.5mm for stock bore, and larger sizes for bored engines. Stock bore is correct for most street builds. Confirm your bore size before ordering if the engine has been machined.
