Focus mk1 more power!! Help!! Thank you
Hello friends, I own a focus mk1 1.6 gasoline from 2003, has made the following improvements: exhaust manifold 4-1 stainless, exhaust line, MSD coil, MSD cables, spark plugs, and pipercross filter. I turn to your wisdom to know what I can do more, to gain power (accelerator body, intake manifold etc etc). many thanks.
