    Item Specification
    Displacement 1.6L Gasoline Turbocharged Direct Injection (GTDI)
    No. of cylinders 4
    Bore/stroke 3.1 –3.2 in ( 79 –81.4 mm)
    Firing order 1-3-4-2
    Spark plug 12405
    Spark plug gap 0.0 –3.2 in ( .8 –81.4 mm)

    I am thinking that means .032 thousandths not 3.2 inches that would be a heck of a gap...

    I was thinking the same as I was reading that. WOW what a gap. .032 sounds right.

    Check out "Spark plug tech" by Pelotonracer2 on another FiST forum..."4-5 o'clock placement"..."grind back the electrode wire 2-3mm so the spark plug flame kernel will induce a more complete burn and increase hp and mpg" paraphrasing here...anyway good thread, good info

    I had two different pics, so... Yes, and... Yes. In different pics :)

    I'm actually glad they banned me. I'd rather see how it is now rather than later.

    I'm not interested in messing with them. Honestly, the best thing I can do, is post all info and all the development I can for the platform here, as well as answer questions when I'm here if I can. Increasing the traffic here while reducing the traffic there is the best "retaliation" I can bestow on them. They were just protecting there vendors, which I understand, but at the cost of platform development. I'm here to push my car further/faster, as well as share my ideas and thoughts to push everyones car to a better state, not to make a site owner cash or to keep a vendor happy. Now... If the site owner happens to get rich while we all further our platform, I'm all for it.

    Notice I don't speak about the product I was accused of selling? It works awesome, I still have it on my car now, and almost no one else has one. Why? Because they valued vendor's over platform development.
    I still win. Maybe when the world is over its self and people put down their calculator for 1sec and actually DO SOMETHING, instead of talking about why it may of may not work, then that product will have its day. In the mean time, its patented.
