As an Escape owner (01 XLT, 04 Limited) I have tried many aftermarket parts for this with trial and error and with me owning a performance shop and chassis dyno here is a listing of the best parts you can add:
Brakes:
EBC Slotted/Dimpled rotors with Series 6000 4x4 Pads in the front.
63500 miles on the truck AND THEY STILL SHOW 3/4 left! (Installed at 900 miles)
Rear brakes: Original ford. 63500 miles to date and still 75% left!
Exhaust: Borla or Magnaflow cat back.
Spark Plugs: NGK (NON PLATINUM!!!!) (Take the damn intake off and label the vacuum lines. ITS EASY!)
Suspension H&R for lowering or BDS Suspension for 2" Lift
Quick and easy HP adder :
www.nextlevelracing.com. The G Box TRI PHASE/Stage 3. It DOES ADD 10-15% HP.
Chips: DO NOT PUT A CHIP especially Superchips in the escape. I used the superchips and kept kicking into theft mode. Superchips is making a power programmer. Keep an eye on that.
Oil: Amsoil Series 2000 with SDF-11 Filter. (In 65000 miles I changed the oil THREE TIMES. Been using amsoil since 3500 miles. )
Supercharger: Kenne Bell of course.
Washer fluid: Prestone Bug Wash (Green). DO NOT USE RAIN-X WASHER FLUID (Orange) it leaves a film all over the escape.
