Brazilian Dodge Dart 76 (similar to 69 usa)

hi,
we use these plugs without any problem. We (my friends and me) used to buy Ap5fs plugs (ngk). But now, bosh are much cheaper. 2 friends are using in their car and are satisfied.

some others friends are using rf11yc (champion).. but they cost almost 2 times than bosh.
i read this whole thread, amazing work my friend, you are a big insperation to alot of us, please let me know if you need anything. if there is something you need that you cant get there again like brake shoes, maybe we could figure out a way to get something to you through the states. im willing to help you out. keep us posted like always. -travis
