I second this, I put one on a 2005 Ford Focus from a 2011 F-250 2wd, with that and warm air intake mod by putting a 2012 Focus MAF adapter and air filter, I took my Focus from highway epa of 29mpg to 38.5mpg everytime with speeds between 50-60mph
This was the second Focus I did, the first one (same model) I used 6in deep lawn edging!
