motor differences
I have been searching for a while on this one. Every thread that I have read that mentions the differences of S4 and S5 engines only state that the intakes are different and if it has EGR it is S4. The only thing I have found to help determine which series a shortblock is that the spark plugs aren't located the same on S4 and S5 rotor housings. Mazda moved them on the S5, but I can't find an info on how they moved them (measurements). Does anyone have anything else?
