Item Specifics

CMR Gasket . Receive 1 ( Copper coated ) High-performance racing quality 40mm Intake gasket made out of a very flexible & durable material measuring almost 2 mm thick which makes it the thickest intake manifold gasket on the market. This gasket is ( Port-Matched ) to the cylinder's intake so as to not restrict air flow like stock gaskets do in return you gain free-flowing airflow for increased Horse power and performance.

These gaskets are for 40mm intakes and will not fit 32mm intakes.

CMR Copper coated gaskets:

CMR 2-Stroke Engine High performance COPPER coated Gasket for performance and superior Seal

Malleable: Copper is stronger than any composite head gasket yet still malleable so it conforms to the sealing surfaces. This strength-malleability combination is, more than any other attribute, the ‘selling point’ of copper as a head gasket material over other materials. While the advantages of strength are self evident, the benefits of a malleable gasket body are somewhat more nuanced. Simply put; conformity makes a tighter seal which will show up in lower leak down percentages.

Conductivity: Copper is the standard for conductors, in head gaskets we don't care about electricity but we do deal with heat. Superior conductivity benefits performance and racing engine builders in two primary ways: A. block & head temperatures are more even. B. Combustion chamber hot spots are dissipated quickly. Cylinder block/head temperature parity is an aid to tuning, though frankly, it's a minimal factor until you reach the narrow end of the tuning window. The big advantage of conductivity is in the combustion chamber area. In and around the combustion chamber standard composite head gaskets and MLS head gaskets are somewhat insulated from the cylinder head and block by the facings and coatings respectively. Heat related failures occur more often with composite and MLS head gaskets than with copper because the heat is trapped within the gasket body allowing hot spots to intensify, whereas the copper being both a better conductor and having direct contact with the block and head (remember metal-to-metal) transfers the heat to the heat exchanger, aka the cooling system, through the head and block.

Elasticity: Another interesting feature of copper, this benefit comes into play when you're out of the tuning window far enough to actually damage the head gasket. Copper coated gaskets have a 25% coefficient of elasticity this gives the user a ‘safety factor’ not available with other head gasket materials.

Superior performance and sealing power.

For 66/80cc engines with 8mm studs.
