Hi there everyone, I am thinking about maybe changing my coil pack and plug leads on my 98 2.8Q as it looks like they are still the original ones. I am hoping possibly for a bit more preformance. The car has done 113000 miles. Do you think it will need doing?Has anyone else changed theres and did it make any differance? If i do change them is there any recomendations for any type of leads. any advice welcome.
