13B 2mm Apex Seal Spring Set for Rx7 and Rx8 from 1986 - 2011.
Do not be fooled by aftermarket home-made apex seal springs which are not stock, they come in a big roll, and they clip them off to size, they are not even heat treated.
We only use the stock Mazda apex seal springs, these are the only ones that should be used, some companies would sell you their home-made springs as usable and offer the stock springs as "Race Springs" and charge an arm and a leg for them, however these so called race springs are simply OEM Mazda.
Please choose 6 short & 6 long springs for a 13B engine, or 9 short & 9 long springs for a 20B application.
