    Searched and found everyone likes Bkr6 and 7e plugs on 1.8t cars.

    I'm using the NGK iridium right now, runs like a charm.

    Don't use the multi electrode plugs.
    Get a standard resistor type or an iridium. Stay far away from the Bosch Platinum +2/+4 stuff.

    NGK's are the way to go. I had a set in my 12V and they worked great. Stay in your stock heat range, unless you're boosted or sprayin.

    I don't know what the N/A cars are running for a plug gap. Check and see if there's a gap recommendation under the hood on the emissions sticker.
    Other than that I don't know. ... I'd check my repair manual, but it went up in flames w/ the garage.
