Apex Seals

[RETed]

Personally, I think almost every other aftermarket apex seal is CRAP.
I use and recommend Mazda OEM.
For super high boost / power applications, you can start to look at the ceramics, if you can stomach the $1,000+ price tag for a set.
Ceramics have no real advantage for street cars running under 20psi of boost and making under 500hp.

The older 3-piece design was more prone to damage.
The newer 2-piece seal is stronger (along the height of the apex seal).
The newer 2-piece seal should last longer due to it's design.
The sacrifice is sealing was very minimal; there is no reason to want the older 3-piece apex seals anymore.
