Yea, our bimmers have coils that go right into the head. If you want to upgrade ignition you have to buy plasma coils. I seen them for around $500. They provide a 100% gain of secondary output to the spark plugs. This provides faster combustion inside the chamber so torque is available sooner.. resulting in a smoother more responsive ride.

Ditto. Don't trust bavauto with their overpriced stuff that will make your car smoother/faster/etc. THey're just trying to make some money. Whatever it could possibly do to your car wouldn't be worth the money. I remember looking at those in the mag, actually... It added such a miniscule amount, it was laughable! As for the good of your car... I don't believe so. Driving it well would make a much larger difference, if that's your concern. I believe the exhaust did more for performance... But I dont recall the price being worth it. Ask them for a mag, they should give you all of the info you need and you can compare that with the price tag.
