im having problems trying to find out what plugs and wires to get......

what exhaust to get.....

and if i should cut my air box to throw in a cai cone filter in to it.......what is the air tube going from the box to the exhaust manifold doing?.......can i just leave that there and just have a con filter or do i need to just leave everything alone?

and i dont know what else to get to just bulid up my motor and make it run better and have more power......

i dont want turbo or nos im not wanting like full race power just a little more and maybe when i get a lot of money saved or income tax i can get the damn thing fully built......
