SCR Race Seals can handle more heat than the standard Mazda Seal. Standard seals will deform under extreme detonation thats if they dont break first!
These seals don't break, crack, or chip.

Standard seals where designed for standard use, they can be used in Hi Boost applications but the life of the engine depends on the tune and fuel being used.

SCR have developed apex seals that can handle the abuse of drag racing, big boost applications.

SCR 3mm seals use SCR dual race springs.
