2007 Saleen Parnelli Jones 4.6 3 Valve spark plug replacement.

[SCALECRAFT]

Hi All

2007 PJ, 5,500 miles on the clock. 1st plug change due to age.

What plugs are people using in this engine?

Saleen pumps this up to 400hp, naturally aspirated.

Saleen uses Autolite HTO. Chance of breaking Autolites as in the Motocraft plug TSB?

Thanks
Steve
