Ignition coil HITACHI or HUCO

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.

I got it. All good now. I swapped a Meyle coil (probably original right?) Out for or a used known good Huco. Knock at idle is GONE and she reves right up!

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).

glad to hear its fixed i had just recieved and replaced my coil to day(mine was HUCO brand)! And the car fires right up now in rainy or wet weather.

it sounds like a problem im haveing with my ignition coil, i could be completely wrong though but anyways an easy way to test it is to start the car and mist the ignition coil with a spray bottle if the car shuts off u need a new one, i got one from germanautoparts.com for only $60 plus $10 shipping and i got it practically the next day.

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!

I used to use the HUCO brand single coil on my old 8V and it would fail every year.... My parts supplier now only sells HUCO when they can't get the BERU units. I have a BERU on my VR and def a better quality piece. I think I went through 4 coils in 5yrs with my old 8V... eventually I kept one ready in the car "just in case"

Yep. The codes don't lie, the coil pack is bad. I swapped it into my wifes 04' and the CEL/ misfire was right there with it. The guy bought it somewhere local but doesn't have the receipt/ record, so he's out $175.
