Minnesota Focus Owners Club

I know some of you guys avoid FF so I'll be nice and offer you the same info

There is good reason when I say to stick with Motorcraft or Autolite spark plugs, and here is why:


Autolite XP5364







Bosch Platinum +2 4315








NGK Iridium IX TRX5IX 7397





Looks like one just doesn't fit quite right eh.
I'll order some more and test fit them and be back.



zetec master spark plug list

First, this list includes plugs that are either 25mm (.984") reach or 1" (25.4mm)reach, be sure to check which you are thinking of buying.

I still have to get proper info on heat ranges, which vary by manufacturer, and link them in.

List is a work in progress just like the pictures.

List can be viewed here --> http://spreadsheets.google.com/ccc?key= ... FFYKeZdQMg
