I've heard about these but do they even make a difference?

 

It's not a worthwhile investment in my opinion, the Honda coil is capable of producing a 50,000V spark, more than enough to ignite air and fuel under heavy boost. Newer Honda coil-on plugs are capable of even more.

It's good to have ignition control, but the stock coil puts out more than enough power.

 

Most of those systems only really have multispark up to a few thousand rpms.Stick with the stock system.
