Recommended spark plugs for a 60,000 mile 1.6L 2002 Accent?

My 2002 Accent (1.6L) recently hit the 60,000 mile mark and I had the
recommended maintenance done yesterday. However, The spark plugs didn't
get changed because I didn't want to spend an additional $100 on the
dealer's platinum spark plugs (+ labor fee) as I can change them myself
for far cheaper.

My question is what spark plug (part numbers if possible) do you recommend
for this high-mileage car? Should I just go with some platinum spark plugs
or just use the copper-core plugs that are recommended in the owner's
manual (e.g., Champion RC10YC4 and NGK BKR5ES-11).

If I go platinum what is the real difference between say NGK's BKR5EGP
"G-Power Single Platinum" and their more expensive "Laser Platinum"
PFR5N-11.

Thanks

 

The factory plugs in an '02 Accent are regular copper, not platinum, and
I'm not sure why the dealer would want to install platinum. Of the plugs
listed in the Owner's manual, it's my opinion that the NGK is the better
plug.

 

My experience with a wide range of cars is that platinum lasts longer
and takes less voltage to make a hot spark. It probably makes more of a
difference in high performance cars. Assuming that no blower or nitrous
which would mandate copper.

 

When I installed Platinum plugs in my accent, there was a noticeable
improvement
over the stock plugs. I would recommend doing it, takes 15 minutes.
I think I paid about $40 for the set. I would do it again, better
mileage for starters.

 

$40 ???????????, Bosh Platinum+ are $3.00 each, $12 a set, did they also
installed them ???

Bosch has four platinum plugs listed from $3 to $8 at Advanced Auto. They do
not tell what is different, but some are pre-set gaps.

 

Unless you are into racing, the +2, +4 really does no make a difference.

 

They don't make any difference, period. In fact, the extra electrodes
inhibit flame spread, which means that they're likely to be more
detrimental than beneficial. The only advantage to them is to Bosch's
bottom line.

 

If you want to stay with copper plugs, NGK's V-Power plugs (under $2
each) actually perform better than platinum plugs, they just don't last
as long.
