ps
whats wrong with bosch plus 4s?
they may be lighter or the same weight as your stockers, but the rotational mass is moved further out, which takes more power to make it move...??? or something like that...also your contact patch is prob wider....and the plugs r garbage

misfires....amongst other problems
Our cars DON"T like Bosch products... period. Unless its a cabin filter. I think the plugs have something to do with not being able to gap them properly because of their crappy design. Duratecs are picky about plug gap, wire, etc.
SVT stock is a high 15.3 (I think) with a GOOD driver.

i disagree about the plugs. rotational mass moved out. i guess that makes sense. since there is more wheel and less tire,but hey im happy with the performance now. i expected 14s after the flywheel replacement.but i would have to assume y-pipe w/o cat should knock off a tenth. when your dealing with @200 horse it doesnt take much. roughly 10 horse = one tenth.

Wow... where'd you educate yourself from?! 
1) Bosch plugs are PROVEN to be BAD for our 2.5L Duratec
2) 200 horses? Nope... to the ground 160-175 depending on driver/conditions
3)Y-pipe w/o a cat... won't do anything on yoru time. Intake? If your car can't suck in more air.. it can't technically release it any faster.

i think it has been proven that having no cat or a gutted cat with high flow y pipe isnt as effective as having a working cat...???

plus 4s proven to be bad? who proved it? maybe on forced induction car? deleting all those nasty bends AND the cat with a bandrel bent y wont help?? because the intake wont suck enough in? i thought the intakes and maf were ok until you start really making power. an engine is an air pump basically. right now the bottle neck of my air pump is the cat-back. get rid of that bottle neck and the air pump can pump more get it? if anything i might lose a little low end torque by opening up the exhaust.

I agree, but I'm sure he wants specifics as to WHY they are "bad".
2) 200 horses? Nope... to the ground 160-175 depending on driver/conditions
I doubt he meant FWHP. I would assume he is talking at the crank.
3)Y-pipe w/o a cat... won't do anything on yoru time. Intake? If your car can't suck in more air.. it can't technically release it any faster.
A highflow y-pipe w/ or w/out a cat should still improve power throughout all rpms. And technically, if the exhaust is a huge restriction(as the y-pipe IS with our cars), then it CAN release it faster without any form of "intake".

Ahhh.. right. Thats where an Intake will not benefit unless exhaust is combined.
