does it matter what kinda sparks i use to replace my old ones?

An example would be iridium spark plugs, the centre electrode is not the same as the standard plug with a soft core, the iridium core is far more resilient to the erosion of the high voltage spark, standard plugs use a soft metal core that will erode away rather quickly, say 20,000Kms with iridium plugs rated to 100,000km's

Plug charts will offer a variety of plugs from standard to long life, long life are better value in my opinion.

i have Bosch Platinum+4 Spark Plugs, should those work for my car?

just as long as they are the correct heat range for you engine.

is it possible for you to get me a chart for the heat reange on spark plugs.

You can down load one direct from bosch.
