86-95 Rx7 13B 2mm Cryogenically Treated Solid Corner Seal Set (ARE88-C)
This is an excellent upgrade to any engine. These are desirable under high boost or nitrous applications. This was designed by David Atkins and has been patented.
This is a one piece corner seal. These can be used in place of the 2 piece Mazda corner seals with plugs. Can be used with the wire type corner seal spring or the 93-95 HP wafer type spring, which is recommended.
Mazda basically copied our design with the Rx8, getting rid of their faulty rubber corner seal plug and opting for a steel one basically making their corner seals solid like these.
The cryogenic treating process creates a denser, more uniform grain structure that allows heat to be dissipated more quickly and uniformly. This tighter molecular structure also increases strength, wear life, and fatigue life.
Do not use these with lapped side housings.
