Does anyone know what the safe redline is for the 2.5L I4 ranger engine? I just bought a instrument cluster with tach to replace my old one without a tach and I'm curious whats safe for these motors.

this is kinda changing the subject, but it still has to do with the four cylinders, does anyone know why ford decided to put two spark plugs in each cylinder? The only thing I have a problem with is it makes changing spark plugs a pain in the rear end.
