Nissan GT-R Cometic Head Gasket By Cicio Performance
We offer these gaskets in two sizes, 96mm for stock bore setups and 100mm for 4.1-4.3 builds!
(Custom sizing is available just give us a call and we’ll make it happen)
The Cometic MLS gasket:
is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, it’s ability to rebound, and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.
These Proprietary Cicio Performance Cometic headgaskets delete the “porkchop” coolant passage that you normally see on the oem headgaskets.
We did this because that is notoriously the weakest part of the oem headgaskets resulting in headgasket failures, barring you from driving your precious GT-R!
The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.
The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
