Best ignition coil for M10 with DCOE40 webers?

I have a 1982 318i now with twin DCOE 40 weber carbs.
On cold mornings it takes a while to start and i'm just wondering if upgrading the ignition coil could help it fire up quicker?
It already has factory electronic ignition - I'm just talking about a hotter coil.
And if it would indeed help, any suggestions as to what coil would be the best (bosch red, MSD, other...) ?

Cheers.

I had a Bosch on my old 02 and that worked fine.

i Don't know that will help you to easier starting engine... If i can help you i have new Beru zs 106 ignition coil on 316 with weber 32/36 and water choke it starts normal any time. The price i have pay it was about 30€... I think that isn't your problem. I can see that your carb have manual choke... do you assembly it properly? if you are, you just need to pull gas full one time and than start engine without touching gas pedal. If you can't start on this way then somewhere is problem...But i think that the last problem is ignition coil, that part is just work or not work.. you just need write one, which you have. If your choke is out of function, pump your gas pedal three time full before starting engine and when you start engine push gas pedal 1/3.
When you car is on working temp. is then everything alright? Misfires, back firing noise...?
