I am looking to increase my mpg and my hp with some mods to my Zetec 4 cyl. I am looking for like 250HP max. I have an ATX tranny though. Any recommendations? I also saw Sleepz mod-ed air intake, whats the difference between that and a cold air? Which is better? I am a college student and looking to upgrade piece by piece. Please help me out...


btw... I love this website!!!!


1999 Contour SE, Zetec 4cly. CAI with stock air box, velocity stacks on CAI, optimized HP exhaust headers. Goal: HP somewhere around 175-225. Stock look. Nice interior.
