I have that jack too came with the axel stands, had it about 6 years ever since I had my mk6 fiesta up on its ford jack and it broke, lucky I hadn't taken the wheel off before it dropped.
The zs is looking good, mine is a red one and liking some of your ideas lol.
I've got a spare zs in the garden ive been stripping for mine so what is it your after and ill see if it has one on?
Cheers - there's a small bit of plastic tube that connects the bottom of the airbox across to what I think is the resonator ... That's the bit that's missing - but I think I'll just get some tubing and clip it in place.
