Mazda Competition's 1974-85 12A (3mm) Carbon Race Apex Seals are specifically designed to replace the stock cast iron apex seals in rotary engines operating near, or above, 8,500 RPM. These carbon apex seals are a one-piece design, 3mm in thickness, and must be used only with our special Race Apex Seal Springs. We do not believe these seals are appropriate for turbocharged applications because of their fragile nature if subject to detonation.
Price is for one (1) seal. Three (3) required per rotor.
THIS PART CANNOT BE RETURNED FOR EXCHANGE OR REFUND DUE TO ITS FRAGILE NATURE AND POSSIBLE CUSTOMER MISHANDLING
