Ignition coil HITACHI or Bremi

Did this conversion on my 2001 Audi A4 with a standalone. I ran it with stock (3ms) dwell and up to 5ms dwell and didnt notice any difference. I was running Hitatchi coils before and would notice slight bumps in idle. Now all I hear is smooth butter at idle.

The old AWD hitachi coils are far more reliable in my experience. I would not change to the awp style from the bolt downs. I have had ~8 failed AWP coils over the years on my 2001 audi/2002 gti and I have 8 hitachis now in my 2 1.8t's for a few years now and no hitachi failures. This is with track days on the gti. They also bolt down so you won't have them popping up on you whack a mole style like the awp ones sometimes do

Don't replace ignition coils until one or more gives out, then I would look into replacing them all with Hitachi E ignition coils (bolt-downs).

To make a story short, and have a happy ending like me , just buy the 1.8 T coilpack (coil-on-plug x 4) manufactured by Hitachi (Japan). They have the top of the plug filled with some ceramic epoxy-like stuff that seems really sturdy and heatproof. I bought them at ECSTuning.com over a year ago, and they haven't failed not even once.

best ignition coils ever. i've been through two other OEM revisions before finally getting the Hitachi bolt-downs from ECS.. and i've been misfire free for about 6 months now!

just put hitachi's in my aww. literally 2 miles after i got it chipped, #2 and 3 blew out the older styled black ones that were in there. no problems with the hitachi's yet

Stick with the Hitachi coils. I only had one fail in 80K miles on my car and 40k of that is BT.

I had the snap in Bremi coils in my 2001 AWW and I replaced them with the Hitachi coils. It smoothed out my idle quite a bit.
