I'd like to suggest people list what coils they have too, though I know not everyone is as anal as I am about that, haha.

B7:
Octane: 92 (boo washington)
Tune: Stage 0 (stock)
Stock Fuelling
Elev.: ~Sea Level
Plugs: BKR6EIX-11
Gap: .044"
Coils: 07K-905-715F
Pros: Smoother idle
Cons: None

B6 (1.8t):
Octane: 92 (boo washington)
Tune: APR Stage 1
Stock Fuelling
Elev.: ~Sea Level
Plugs: BKR7EIX-11
Gap: .044"
Coils: 07K-905-715F
Pros: Smoother idle, Gutsier low end, Stronger boost onset, Smoother power delivery
Cons: None

I found my B6 especially REALLY benefited from the larger gap. Having the tune, it REALLY helped with the larger gap providing the stronger spark when the boost pressure crept up towards 19. I peak at 19 and hold around 15 on my 1.8t with these coils and haven't had a SINGLE issue in over a year with this setup.

With my B7 the results were less exciting. I actually ran a .044" gap on the regular coils (not sure what part number but they were a few years old) and the car ran great, no breakup or misfires, even though the coils were older. With the new coils there doesn't seem to be much of a difference. To be honest, on a stock engine, I'm not sure the larger gap does a whole lot. My B7 feels really slow compared to my b6 even though power levels are roughly on par. I think the power onset is so much difference, the greater amount of boost makes the car FEEL faster even though it might not be.
