Valve Springs Mazda Miata 1990-1997, 1999-2005, Ford Escort(1991-1996)

Upgrading your valve springs is a necessary component when modifying your Mazda BP engine.  The OEM seat pressure is intended to work with relatively light applications.  If you plan on pushing your motor beyond the 7k redline you’d better have the necessary components to hang, and we’ve got just what you’re looking for.


There are three options to choose from depending on your usage:

Single spring - 8000rpm

Light double spring - 8400rpm

Heavy double spring - revs to 9000rpm

Kit includes

  • 16 or 32 springs
  • 16 Titanium retainers RET-TS60/MA2
  • 16 spring seats, steel SEAT-TS/MA18I

NOTICE: Fits all NA and NB Miatas. NA valves will require the use of valve keepers from a NB engine (not included). You can purchase an upgraded NB keeper set HERE

    Valve Springs

    Great product. Tons of information on them online. Fab9 was great to deal with and had the lowest price I found. I chose the heavy springs for my 99 turbo build.
