Nothing wrong with platinum plugs, but I would stick with NGK or ND.  I've
heard people talk bad about BOSCH plugs in hondas.  The only difference you
might notice with platinum plugs is that they will last twice as long, and
probably cost 3 times as much.

I have a '94 Acura Integra LS (without VTEC). I've been told that platinum
spark plugs won't do well in this engine. Does anyone know why? I used them
for years in my '88 Accord without any problems. I wouldn't think that there
would be much of a difference.

Who told you that?  

I had a 94 Integra LS that had NGK platinum plugs in it and they
worked fine.  As the other poster said, I would only use NGK or ND,
wouldn't use a product from Bosch (or sometimes referred to as
'Botched'.

       '90 Integra.  Have used NGK, ND, Bosch Platinum, Autolite (yes) and Delco.  The Autolite and Delco lasted the longest.  The Bosch were good but didn't last as long.  All worked just fine otherwise.  Suggest that pure synthetic oil might be the difference.  Fewer carbon deposits.  VTEC and higher rpms from more modern engines might also make a real difference.  The '90 'Teg was an understressed engine (caveat emptor).
