Ive just bought a totally standard mk5 zetec S, its really tidy and looks great.
Im going to get the cambelt and water pump done on it, but my question is, what do these really benefit from?

I know the basics about them but havent had time to look deeper into it.
Im not after a full rebuild, but just some touches.

I think 4 new speakers would benefit it, and ive heard they sound great with an induction kit?

Anyway, what would you do if it was yours and what do these really benefit from?
cheers.
