Cryogenically Treated

86-95 13B OEM Mazda Side seals that we have cryogenically treated.

Please choose 12 side seals for a 13B engine, or 18 side seals for a 20B application.

We prefer the side seals Mazda offers which are longer that require hand fitting so that you can attain a tighter fit between side seal and corner seal to allow maximum compression and no blow by. Every rotor is different so it is better to get them longer to custom fit each slot, these are cheaper also than the pre-cut versions. You will need to remove approximately 0.05"(1.28mm) from each side seal. Slowly remove the material and try fitting them til you get an ideal fit of 0.002" - 0.006" (0.05mm - 0.15mm) with a maximum limit of 0.0157" (0.4mm).

Patented Cryogenically Treated 3mm Solid Corner Seals, for use on all 12A and 13B 3mm applications.

Able to choose 12 Solid Corner seals for a 13B engine, or 18 for a 20B application.

12A Cryogenically Treated Apex Seals. All of our apex seals undergo a heat treatment, these apex seals are taken one step further with a cryogenic treating process which 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.

All of our apex seals undergo a heat treatment, these apex seals are taken one step further with a cryogenic treating process which creates a denser, more uniform grain structure that allows heat to be dissipated more quickly and uniformly.

Six Mazda OEM Rx8 Cryogenically Treated Apex Seals, springs not included. These will not work for earlier 2mm rx7 engines.

Cryo treating this part is great because these ride over the extremely hot exhaust port inside the engine. Cryo treating these allows heat to be dissipated more quickly and uniformly.
