FSI Coils Chime In

[LightningLou]

So I'd really like to hear from all the people that have done the FSI coil conversion with mainly stage 3 cars... Did you have any misfires at idle or at WOT from before the conversion that cleared up after switching to FSI coils due to tiny plug gaps, cold plugs, high boost, etc.?? I'm thinking about doing this swap, but was interested to hear if it's actually a worthwhile mod from those that have switched. Also, how reliable have these coils been to you so far and have you had any coils fail or CEL's so far? Also, is the dwell necessary to adjust in the tune for performance and reliability? I hear it's necessary and it isn't, so which one is it?

when you switch, make sure to get RS6 bolt on coils, the bs 2.0t/R8/etc push ins that require adapters will leak water into the coil holes since they're not really sealed at all.

No misfires, cheaper coils, removes icms from system, supposedly slightly hotter spark. If you have a few week/bad coils then definately do it. If you're good at wiring there are some good diy threads.

They all leak with any adapters? Any good places to find the RS6 coils at? Thanks man

Well I am pretty good at wiring as I built aircraft wiring harnesses for a living a while back even though I dread it lol. Not sure if I have any dead coils, but I do get random cold misfires sometimes at idle. Did you have any misfires before the swap that cleared up because of the hotter spark from the coils? Thanks man

I've tuned many cars who have done the conversion.. no issues at all with misfires at any point in time.. no extra grounds, no changing on dwell times... only had one issue where 034 wired the ICM delete wrong which we luckily caught before pulling the motor back out.

It's not a mad as much as it is just preventative maintenance. Reliability wise I haven't see any issues with them either... one good friend of mine put approx 120k km on his set without issue. I've been rocking 2.0T coils in my BMW for about 2 years now also without issue.

what julex said...I got harness adapters and icm delete connectors from 034 and picked up the rs6 coils.....they drop right in and use the same seal ring...easy peasy

[S4James]

what year rs6?

[Speed4Avant]

I've had the conversion for over two years, had one coil die on me in that time frame. You can just put some sealer around the holes in the plastic touareg adapters and it won't leak.

[julex]

what year rs6?

c5 rs6, 2003-2004 I think is the vintage.

[vavJETTAw36]

+1 for RS6 coils. You wont be disappointed

[axnjaksn]

I believe its 2003 only in the US right?? for RS6...either way you wont be disappointed....clean easy and sealed...

[LightningLou]

So sounds like RS6 coils is the way to go... Are you guys noticing any performance improvements or smoother idling perhaps or less random misfires at idle on e85? I am hoping I can cure my minimal cold start random misfires with these new coils and wider plug gaps if it is putting out a hotter spark.

[S4gasm2.7t]

Just curious, as I have the Ecs adapter plates but I wired in the connectors. Will the rs6 coils bolt down properly.

Similar here. Thankfully the thing was fine before the swap so I knew it was something to do with the new parts. Easy fix.




RS6 coils defeat one of the big benefits of the conversion, cheap ass easy to get coils.
The adapters wont leak if you get the right ones. If only somebody, possibly on this forum, made nice delrin ones that were cut to the same shape as the valve cover and had the hole in the right place

[LakeTahoeQuattr]

Why do they have to be "RS6" coils. Arent all v8 bolt in coils the same.

[S4tech2]

To answer your question of if I had misfires before the swap, yes I had misfires in high boost (20psi+) and after the swap that issue was resolved. I'm not good at soldering and it caused issues for me but if you are good at it then it's all you.http://www.audizine.com/forum/showth...-Solder-method
This even gives you the part number for the coil adapters through vw. I got my coils and pigtails for nothing so I was only in it for like $45 for the coil adapters.

Because it is much cooler when you ask for RS6 coils instead of VW 2000 Golf/Beetle doesn't it Yes, they use the same ignition coils so not even V8 haha.

Part # 06B905115E for original Hitachi made coils. There are other revisions but Hitachi are regarded as by far the most reliable.

RS6 (and many more Audi/VW models using this coi) part# 06B905115E can bu purchased readily anywhere and genuine website lists them for 30.50 a pop for example. Not a big price difference to have any argument over.

So... spend extra on adapters (first argument goes out of the window then?) and then a tube of silicone to entomb the coils with goop so it doesn't leak? Great .

And you still have a coil with very poor heat exchange interface since there is no direct connection between coil head (where heat gets generated) and engine head to take the heat away. A lot of 2.0t coil failures historically are due to coil overheating and swelling/blowing up due to lack of heat sink. Rs6 bolt downs don't have this problem since the whole bottom of coil is touching machine aluminum surface which takes heat away.

Been there, done that. 2.0t push ins with your vanilla CNC coil plates. Found first two plug holes full of weird powder at plug change on time... scratched my head, figured must be water. So after next torrential rain drive session I popped one coil and found 2" of water in there, a miracle the cylinder was still firing... Promptly changed to Rs6 coils, sold plugs+adapters used and it paid for Rs6 ones.

Will these bolt down coils work on the 1.8t head?

I was sort of looking forward to putting in the red R8 coils so that I could have engine coil stance

Exactly. And exactly. Wonder who that guy is...

Yep, the RS6's are only twice the price and this does obviate the cost of adapters (a hunnert bones). As I recall, at the time we started with the 2.0t coils the RS6 coils were quite a bit more so the 2.0's were the way to go. The red top coils do look better (like that has any bearing on how we mod our cars) and if you get the right adapters that Rob was referring to, look even better and are sealed WITHOUT a buncha goop.

I think you have the heat transfer thing wrong. The heads get warmer than the coils so insulating them from the heads makes them last longer. In their original application they are not sinked to the heads. I've not heard of a single coil failure with the Delrin adapters.

[y3ti]

Over 2 years on my delrin adapters and 2.0t coils, no issues here. Haven't had to replace even 1 coil.

[M1NDCRlME]

1 year and 9 months (maybe its 2 years and 9 months? i cant remember) with the ECS kit with aluminum adapter plates and 2.0T coils and have had ZERO issues. She is my DD so it was money well spent.
