Pics wanted: 7A valvecover with TFSI coils

[prj]

I would recommend running the longer ones, especially on E85.

On gasoline you should be fine with 1.8T ones.

Where's the beating a dead horse icon???

maybe the moderators could put a "flogging a dead horse" smilie up....

I think its a bit clearer now.....

Yes, Hamish, your car was one I had been thinking of when I said that 1.8 coils can definitely support big power.

...But perhaps the power limit is near? Or difference in MTBF?

<EDIT>

Here is what IE has to say about the difference in the description for their adapter spacers...

The FSI/TSI coilpacks allow you to run a larger spark plug gap, while maintaining a strong spark output. Testing has shown a smoother idle with these coilpacks, increased off boost power, and in some cases improved fuel economy.

M, that is 06C 905 115M, seemingly available...http://genuineaudiparts.com/parts/in...&siteid=214407

I have finally got around to pulling the numbers off my coil packs. They are 06C 905 115M which ties in with what you have found. I prefer the look of the shorter ones even if it takes extra effort to fit them.

Engine made 700bhp at 2.2 bar with no ignition issues so they seem up to the job so far.

Short story...if you want the short red coils, get 06C 905 115M.
If you want the long red coils, get 06E 905 115E.

But just to reiterate, the shorter coils may not perform as well...

Because of the requirement for the 2.0T (FSI) to do a leaner burn, the spark must be hotter. By using these more capable coil packs, 1.8T drivers have been able to increase the gap on their spark plugs to .040" or more. This gives a stronger spark with many advantages including more complete combustion.

Even though big power has been made on the 1.8T coils, I'd hate to compromise on performance just to have them sit down further...

Mike, 06E 905 115E is the ones I also use, and they are the longer version.

[europeanme]

Don't think so. The 115Es that I am running are the taller version. Never seen a shorter red version.

these are what I will be using....

[Wheeljack]

confirm with Bill they are shorter as these are the ones Steve and I got from genuineparts....

So you have 06C 905 115M and they are the long ones? Can you confirm length and part number?

I had them on my 1.8t a4 and mine were short, like normal 1.8t coils, but red.

Ok, thanks.

[Wheeljack]

Ok, 06C 905 115 seems to be NLA. What is the latest rev?

Just regurgitating from higher up...there are indeed shorter red coils. They were used on 3.0 from the early 2000's, and possibly others. These are what the 1.8t guys were using to bling up the bay back in the day.

And also quoting Kai (Masterblaster)...

06C 905 115 from 3.0l (there are different revisions)

These are short red coils.

That said, there's been a lot of discussion regarding the longer, newer coil packs for the TFSI engines having higher performance and allowing running better gaps. So I'd stick with the longer ones. Search Audizine threads, tons of info if you can sift through the BS.

That is why so many companies sell the 'spacer' to use the longer coils on 1.8t's and such. Wouldn't make much sense if the only reason was to get red coils, since you can get short red coils and plug and play.

[europeanme]

for your info Thomas, I'm not sure you can get shorter red coils.....they only have them in black....

@ Steve, those coils look pretty spot on don't you think...

[Thuppu]

Thats that sorted then!

Can you please check the brand and part number on your coils? Would be nice to know what the short red ones are.
