P.S. I am very happy with my 1.8 Zetec.

I just need it to go faster and hold the road better without breaking the bank (no throttle bodies).
First up comes a Panhard Rod next week, an easy fix.
Mine is the 'silver top' from 2000 and as yours is the 2001 I'm guessing yours is the 'black top'
I went for the librands sport manifold and sports exhaust on mine plus a K&N filter which I'm really pleased with - a bit more poke and a nice bit noise
If yours is the 'black top' I think I have the K&N filter part number somewhere as I posted it a year or so ago to someone - PM me if you need it and I'll try and find it
