The Black Diamond Head Gaskets are sold individually. Please select from either 18mm or 20mm dowel. Engines built 2003-1/10/2006 will require 18mm. Any engine built after 1/11/2006 will require 20mm.
The coating seals and impregnates into the mating component surface where it decreases friction forces and allows controlled sliding of the mating components relative to the gasket without fretting or damage to aluminum engine components. The Black Diamond coating is soft enough for cold sealing and features maximum adhesion, increased durability and temperature resistance and is also resistant to engine fluids including gas, oil and coolant.
This set is for a single head gasket ONLY. Don't forget to buy head studs!!
