Fixed! It was the plugs, I just put in the set I ordered from ebay that you provided and now I can't get it to backfire at all. Thanks a lot!

Here is what the less than 1000km new genuine Ford ones look like:

I am no mechanic, so I am asking this to get a better understanding. The spark plug in the pic looks fine to me. What is wrong with it? What do you guys see that I don't? Is it the gap that is to big?

Yeah Marco, 1.1mm instead of 0.7. The larger gap means the spark gets blown out under higher boost levels.

If you get a spark booster kit installed and keep the larger gap you get a smoother drive and probably other things I forget about (better burn - power?) but it's easier and cheaper to just use the smaller gapped plugs instead.

I want one of the spark booster kits. Herrods kit is exxy but plug and play, no splicing. Ralph runs a unit that does the same thing.
