The NGK 7100 is a G-Power platinum spark plug, sold here as a set of eight for the 4.7L V8 Jeep Grand Cherokee from 1997 to 2007. Its platinum-tipped center electrode is the step up from NGK's basic V-Power copper plug, aimed at longer service life and steadier spark under heat. For a 4.7L V8, eight plugs cover the full engine in one job. Compared with iridium plugs, platinum wears faster but costs less per plug; compared with copper, it lasts longer between changes.
