The stock autolite 5143 is all that you need. I ran that or the NGK TR6 on my Xcharger'd 2006. Most run the stock plug. There really is no need or benefit to the expensive plugs.
Why have u tried them before? And it didnt work?i wouldn't put a bosch plug in a lawn mower...and that's what i tell every customer that asks me about them lol
