    I've done a search and can only find a few mentions of the adapter plates to fit TFSI coils to a 1.8 engine.

    I know this was something that Bill and Tuffty have spoken about testing but I wondered if anyone else had any more info or test results.

    For those who haven't seen this before, have a little read here:

    2.0T/FSI coil packs

    VWVortex.com - 2.0T Coilpacks and spark plug gap, trying random new stuff.

    *** 1.8T to 2.0T Coil Pack Coversion Kits *** - SEAT Cupra.net - SEAT Forum

    Basically you can run a bigger plug gap with the TFSI coils and therefore bigger spark = better performance.

    Plan to see if I can try this once my engine is back together...

    I know Bill was planning on testing this on the Lupo but he hasn't had the time as yet...

    I'm assuming that you can run these coils on an AEB/AGU large port even thought they normally use bolt down coils?

    Yeah the adaptors bolt down anyway dont they. So they`ll bolt down as the old coils would and the push downs will slip in..?

    What's the advantage of having 2.0 TFSI coilpacks? I don't get it.

    I'm massively skeptical, but apparently a bigger spark gives you a better burn... Doesn't make sense to me, but some people are reporting gains

    They won't work without spacers on TFSI coil packs...

    head is irrelevant as its down to the cam cover that holds the coil packs in...

    I have an AEB head and use the AMK cover... push ins fit... simples :)

    I am awaiting results to see the benefits. I know when i lost my old dumb coils and lost the ICM the car felt smoother. No reason to assume this will be any different, It should in fact be a much larger difference

    I have them already as people say you can run 1 mm gapped plugs and they more reliable

    I've not finished my extra modifications yet to the engine but will report back when its running

    Dunno.. adaptors should negate the need for that but they are pretty cheap on eBay anyway...

    It's just the import tax and time it takes from the US that annoys me.

    Tax very little. Even with the tax the from the US the coil packs and adaptors are as much as just the coil packs alone in the UK

    Mine only took 2 weeks to come

    TFSI packs have more energy so allowing a larger gap to be run giving a fatter spark making combustion more efficient...

    There are a couple of different versions of the adaptors, depending on wether your installing them in an AGU style rocker cover or the later push down cover.

    For AGU and other early cars running the "dumb" bolt down coils with a seperate ICM the conversion is a no brainer. We already now the later coils with the integrated drivers are more powerful, and the TFSI ones are more powerful again, and cheaper.

    The main advantage as i see it is that it allows you to run larger plug gaps. The TFSI coils will happily run a 1mm gap, whereas the older coils (even the latest R revision that audis fitting for free) need the plug gapped down to 0.7mm on higher power cars, and if you try to run a bigger gap theres a good chance you'll kill the coil. A bigger gap means more voltage is required to strike an arc, and that in turn means the spark itself is more powerful.

    One thing to note is that a few people have found issue with the 06H coils from the most recent engines. INA are recommending you stick with the 06E or 07K coils.

    The old style AGU bolt down coils are also more expensive then the later push down ones. When I fit my AEB head next year I will keep my BAM rocker cover I think.

    Is that a 100% 'yes' or a 'No but after testing I will'?

    Ok... now I am confused... if you have a BAM cover why did you want to change it to fit the TFSI packs??? the adapters are designed to fit these covers..

    Bolt down coil pack cover..
    [​IMG]

    Push in coil pack cover...
    [​IMG]

    As you can see the push in type has the screw fixings already for the adapters...

    Tuffty, I currently have a BAM engine but I have an AEB large port head ready to go on in the new year. Before I even started looking at the possibility of using TFSI coil packs I was just going to swap the lot over and keep the AEB rocker cover with bolt downs. To be honest with you, I didn't realise that the heads and rocker covers were inter changable.

    So when I fit the large port AEB head next year I'll use my BAM cover instead of the AEB one. Hopefully that's a bit clearer now :think:

    Bits of it and a while ago. What part are you referring to? Something to do with mixing the heads and covers :)

    Don't worry mate... I have swapped the head twice on my car with AEB large ports and used the original cam cover every time... probably loads of pics as usual...

    In summary, use your BAM cover and all will be good :)
