They claim it adds another half psi if used with the K&N open air filter. So it's just an added 1/2 psi with an aftermarket intake. I am guessing the zetec requires, at most, 250 CFM at high rpm.. So the e-ram boost psi by 1/2 and raises cfm to 750, while a CAI is pulling more than 250 CFM, the e-ram is a restriction, as long as you are flooring it, and be honest, when do you not floor it???, They also bring the fact of the fan shape that it doesn't restrict by more than 1 hp, even saying it MAY give 1hp(bs), but still, it's not a major restriction and it does its job... I think I still want one. They are proven to work, and if one is good, two must be better...right?
