Roush 427R Sparkplugs
I have a Superformance coupe with the Roush 427R. The plugs that are
in the car are Autolite 3926. My mechanic works on Rousch engines and says
to use a NGK 6953 Vnotch. I called a Rouch rep and he said the original
engines manufactured in 2005 came with a Bosch 7556.
What do you guys recommend???? I am not racing the car.
Thanks
