I recently started "tuning up" my cars. For my 2000 Toyota Sienna
minivan, I put
in Denso Iridium plugs. Wow, very nice. The engine responded to it
and feels very lively.
For my 1990 535i, 5 spd, 128k, I put in some NGK ZGR5A standard plugs.
well, but definitely didn't have that "lively," "responsive" feel I
got when I
put iridiums into the van.
Has anyone tried iridium plugs in a M30 3.5l engine? If so, what did
was it worth it? Or should I just be happy my car still runs....:)
