what plugs come in our cars from the factory?
im pulling out tr55 and i don't think that is what came in our cars???

that and what type of wires shoudl i buy and where from?

 

NGK Tr55 is not stock, but they are good to use. Thats what I put in. Stock is Delco, I think. I have MSD wires - our wires are so short it probably isn't a big concrn. But I also hear a lot of good things about Aurora wires. I think they are actually made locally too.
