Ive recently had my fiesta converted from a 1.6 to a 2.0

The engine is still using the spark plugs that came with it so id like to change them

What are the best plugs for a 2.0 Zetec. Its a phase 1 or 2 out of a Mondeo if that helps. Also what are the best leads to accompany them

While im here what are the best plugs for a 1.6 Zetec as my brother is in need of some too

Cheers

Scott
