it wont hurt anything to run a bosch or champion or ac or autolite plug in your motor. honda just recommends NGK because thats what came in the car originally. if you don't have NGK's in the car dont freak thinking you will hurt the motor
though I would rec. staying away from the bosch platinum 4's. The gapping isn't right on them for the application, and they are non gappable plugs. My car ran like absolute garbage when I put them in. I switched back to the proper NGK's and it ran like a dream. Same thing happened in my roommates GSR swapped EG.
