The FXE-24HR-11 (Denso plug) is the one step colder plug for the HR Z's it is the one step colder version of the factory ones. You should stick with the ones I mentioned instead of going with some other brand since going from brand to brand varies greatly and may not end up with the correct heat range. You can buy them at sparkplugs.com .
