Cheers,des.
Audiman used them!! So I guess that means 500 and something bhp!
I thinkas long as you source the latest version of the 1.8t coils, then they're pretty good. I've not had any trouble since I got the latest versions from Vagparts and at £20ish each you can't really complain. However you must not run them under the existing coil cover as they don't like the heat! They will just fit using a 7A and possibly 3B cam cover if your that way inclined.
The Apikol loom fits RHD cars but I would suggest that you're better off sourcing the coilpacks yourself. I made a loom myself and it's pretty straightforward if you don't mind taking the time. It's a lot cheaper that way too!!
Another option is to use GM remote coils like some are trying on Audiworld. These are pretty cheap but you'll need HT leads as they're very similar to the 034 HO coilpacks.

I'm with Des on this one - HT leads are the work of the devil... That 034 coilpack kit might be high performing, but it looks kak IMO... I'm no fan of the 1.8T coils by the way - they don't like the heat. I'd just go with new S2/RS2 coilpacks - sure they are expensive, but how often does highest quality come at the lowest price ?
People freak out about them 'failing so often' - I attribute this to the originally fitted items coming to the end of their lifetime on these old cars. Mine are getting on for ~15yrs with over 140k miles and still working fine. If one or more start to play up, I shall not worry about the expensive of duplicate replacements - as they should give similar service. Fit and forget (for fifteen years anyway).
American 1.8T coilpacks are not the same they are here.
Also, there are at least Febi and some other manufacturer's, which' coils are not as good as genuine Bosch units.
To make things even more complicated, some coils from marble desk (audi dealer's spare desk) are not good. Even the part number doesn't prove a thing.
For 450ish hp / 550ish Nm all seem to work more or less, although the non-good ones don'e live too long.
Some particular batches from Bosch seem to work up to 800Nm.
I fried a couple of coils from customer's car at test runs last summer. They were the good bosch units, but died 'cause of a plug failure. Replaced plugs, and fried coils with cheap replacement units (do not remember the brand). Worked for 1st and second gear flat out, but started to shudder at third. Killed I think one or two so, that it worked on vacuum, but started to nod / stumble on boost, so I drove home with very gentle throttle.
Bought a set of Bosch ones of known good batch, which cured the issue, and car still runs daily, like a baby. 650ish hp / 800ish Nm with 2,4bar boost.
Everything less than 2 bar is considered to be naturally aspirated
Cheers guys! Any "special" part numbers to look for/stay away from?
Stay away from new old stock that ends in 115H or 115 J. Minimum 115 L, preferably 115 R, possibly 115 S (the latest) if you can find them at a good price.
Bremi was the one with the original supply contract that had to redo thousands because of the failures and the recall. (Pre 115 H). Presumably they have the quality control/re-design under control. However, they still don't like a lot of heat, e.g. tracking the car will kill coils quickly.
