Our Apex Seals were designed to not cause premature rotor housing wear; the OEM ones will actually wear out the housings faster than these. In the event that the engine is operated at elevated temps, for instance when running very “lean” conditions such as extreme pre-ignition/detonation due to overadvancing ignition timing: they will deform before they break. This deformation serves as a warning instead of instantly encountering a severly broken engine which occurs with OEM seals. This deformation will cause a loss in compression associated with loss of optimal seating against the internal surfaces of the engine but it will be as simple as replacing the seals themselves instead of the rotor, housing, etc. as isnormally the case with the OEM seals when breakage occurs.
These seals have been proven to withstand boost pressure levels of more than 30psi with proper fueling and tuning. They have seen WHP levels well above 500whp while being safe for engine internals. This is the ultimate internal upgrade for the Mazda Renesis engine.
