what would you all say is the best brand for this parts??

spark plugs: NGK makes some good plugs, and so does bosche.

wires: the wires does not matter what kind you get. i just get what autozone gives me. except the REALLY cheap ones.

cap: does not matter.

now if you plan on getting a bigger coil then you might want to get some heavier wires and a platinum plug. other than that if you are running stock then i really would not worry about much.

he might already have platinum if he has a gsr! mwahahhaa

gsr's are crap, what you need to do is find yourself a 92 ls, and gank those parts from the innercooler submission tank. If you retrospect into the nigulator, you will find there is an abundant supply. Hola if you need anymore help
