first...dont use bosch +4's with an app like that..I would have suggested using some Iridium plugs (oh well, to late) As for wires, there is a large large contingent of wire set makers out there but the name that always sticks out to me is....magnecore

also NGK offers new iridium plugs as well.
have you upgraded the coils on the plugs? I dont know what kind of ignition system the 2zz uses weather a distributor or a coil on plug...but you might what to check out upgrading that side of the ignition as well.
