Re: spark plug cross over

Thanks fun times. Called my dealer today and they told me ac delco 41-993 has been changed to ac delco 41-101. I had the champions r12 pyp and thankfully I cannot get them. Going to buy the m today and ac delco runs fine in my truck,so my fingers are crossed. By the way it is a 5.0gxi b(f) 2002
