Hi Joe, Don't just run out and buy the plugs yet. I'm going to post more feedback on how they perform on my Focus. If they prove to be good over a few tanks of gas, improving MPGs consistently, then they're a better candidate for our older engines. The difference in installing them on a carbed vehicle is that we'll have to tune a bit differently. I'm considering picking up an Edlebrock Air Fuel Monitor to use on the 304 stroker build, pending more feedback on the focus. Greg :) <>< P.S. If I get consistent 2 MPG city and 4 MPG highway improvement, then the plugs will be paid for in 4-6 months on the Focus.

My 63 is running fine (knock on wood) but anything that would save a little gas these days could pay for itself really fast!!! Thanks a million!!
