I always use the ND. or NGK in my Hondas. Check the under hood sticker
for the part number.     bob

I use what my owner's manual recommends. In the case of my 91 Civic, they're NGK
non-platinum. (There might be one other brand recommended in the manual.)

A dealer put platinums in my car a few years ago. I have since changed them out.
I don't notice any better performance. I suppose the platinums might last
longer, but IIRC from reading on the net it may not be enough to justify the
higher expense.

My 91 Civic Si had a set of SplitFire plugs, then recently it started to
miss in low RPMs.  I replaced them a set of Nippon Denso (non-Iridium 3808).
$1.69 at AutoZone.  Now it runs great and getting 31 mpg.

Bosch are overrated when it comes to Platinum.  I read somewhere a long time
ago that the platinum they use is from recycled catalytic converters.  If
you need a hotter plug, I suggest the Denso Racing Iridium.  Iridium is way
better than platinum.

stick with NGK or ND.
save your money and use standard plug and replace every 2 yr.

I have just put NGK platinum's in my 92 Civic. They ran me about $2.50 a
piece (before tax)  That and a new set of NGK wires set me up right...
