Roffle, how do you like the Bavauto coils?

Bumping an old thread. How have the ignition coils worked out for you?

iPhoneEngineer · 06-03-2013, 04:52 PM

Largely due to the discussion here, I never actually got the coils. Consensus seemed to be that the stock coils are quite good. I replaced my spark plugs, which helped slightly but noticeably. Then I had to ship the car to ESS (at my expense—$1100!

) for further debugging, and they found an issue with the tune that was corrected and solved the biggest problem with my car.

Having the nicer coils would be an awesome peace of mind, but the cost-to-benefit ratio is just a bit worse than I can bear. Rather save for an exhaust system or new paint job

.

very much. I believe I picked up some mid-range power, but I haven't dynoed since I've had a boost leak with my initial install

Aren't the Bavauto coils just these with red caps stuck on them?
But I do like the red caps.

I just bought these. Couldn't pass up the price.
