iv heard rumors that the intake manifolds on the 2000 zetec dont create power past 5k or so.. is this true? if so... whats the solution as far as replacing the I.M with lets say an SVT or newer zetec? and would putting an svt header on a 00' zetec be worth it without the newer/ replaced intake mani?.. jus lookin for a few extra ponies...[poke].. btw thanks ahead of time for the help !!!not affraid to shoot reps!
