I am relatively early in my modding of my Focus and I have heard numerous opinions about what mods are worth it and which are a waste.

What was the best engine mod and worst(or least useful) engine mod you have done for your Foci?

P.S. ZETEC and SVT decals are not true engine modifications

the most worthless mod (power-wise) would have to be spark plug wires and spark plugs, but hey you gotta keep the car well maintained.

IN MY OPINION the est mids for the money would be COLD AIR INTAKE,CAM GEARS, UDP,AND EXHAUST OR HEADERS. Maybe in that order too

Worse mods, nitrous ocatane booster,spark plugs etc...etc...

best bang for the buck = UDP

Most HP = cams, cam gears, high flow cat

Good Mods = all the other bolt-ons

mods that do nothing = plug wires

Is a type-R sticker a direct bolton or should I go with the Si decal......??????if used in tandem will my bottom-end hold together

My vote is for a ECU chip for an upgrade.

Honestly for a really cheap mod, a new panel filter wont do crap, however a K&N cone filter will increase throttle response and sound significantly, but if it is performance you are after, you are better off with a whole intake like AEM or Volant

Best is intake resonator removal.
Worst is any kind of forced induction.
