Copper or PLatinum Spark Plugs?
Time for that change in my 2001 2.4 Dodge.
But to use OEM copper or newfangled platinum? I see it written that copper is better for conductivity, platinum only adds long life. I also see it written online that some swear better MPG with the platinum, and some claim that's bunk.
Long story short..... which to use?

i say use the OEM. i tried the platinum with multiple electrodes(took out put Champions OEM back in) when i had my 2004 2.7 car ran worse in my opinion. a friend(an ex-dodge mechanic) told me best to use OEM plugs since the ignition was designed for that type plug

Great to learn by others experience. Thanks for posting. Always one more thing... which to choose???
OEM Champion 440 - RE14MCC5, appears to have been replaced with 470 - RE14MCC5. Both are available with a recommended gap of .050 Is there an advantage to using the replacement one?
On the next level, Champion RE16MC supersedes/replaces RE14MCC5 and has a recommended gap of .040
There's also TSB 08-008-04 which, depending on the source, affects all 2.4 engines or only those after 2002. Mine's a 2001 SE getting it's first plug change at 30,000 miles.
New Spark Plug for 2.4L Engine
The new style spark plug is now recommended and preferred
for use in all 2004 and previous model years that are equipped
with a 2.4L engine. Spark Plug gap is to be set at .040
The new spark plug is more resistant to possible cold
engine carbon fouling.
Note: To eliminate concerns of a possible high secondary
ignition voltage flashover, caused by the thermal set of
the ignition cable spark plug boot(s), to the old style
spark plugs (RE14MCC5), install new ignition cables when
replacing the old style spark plugs with the new style spark
plugs, RE16MC or LZTR4A-11, for the first time.

I have an 02 Stratus with the 2.4 DOHC. Run Champion plugs (P/N 3570) and gap them to .040". Runs like a champ and knocks down 26mpg in mixed driving. Don't bother with the mult-tipped, irridium crap, unless you like spending a lot of money and the car running "okay".
Just run the 3570 and call it a day.
(PS, the autopart stores that I've been too (advance and autozone) do not have the correct plugs listed for our cars. The plugs I first picked up on the first time I changed plugs out, were shorter and cause a lot of hesitation and mis-firing.)
