Having a hard time finding the part number for the water shutters that fit in the Y pipe.
its a 2003 496 mag
anybody know??
also I need the ac spark plug number

thanks

water shutter # 84-807166a-1. They come as singles so you would need two if replacing both. Between $45.00-$50.00 a piece.

acdelco 41-983 I used them in mine before the supercharger and worked great. The stock ones are like 20 bucks for one!!!
