Best ways to increase horse power?
I have a 91 Jeep Cherokee and I want to increase the Horsepower on it. I wouldn't mind it being a little louder or deeper sounding either. What are the best mods you can do to increase horse power? I just want this thing to perform like a beast

Cold air intake. i did it and i can feel the difference. and i diddnt even use a velocity thing. so i guess it doesnt make it "cold" but i dont want my xj looking gay with a cone sticking out. unless someone has found a way to hide it. then i would love to know what it is.

get performance injectors, upgrade your spark plug wires to anything over 8mm. i have seen 12mm wires precut for the 4.0l before, get an MSD ignition upgrade, get a TRUE cold air intake with throttle body spacer and get a full exhaust-headers to tailpipe. that is strait up bolt on power that you will really feel. anything past that is called STROKER =]

I have found a few ways to get more HP 1) k&N air filter your choice of cold or not 2) a proformance chip if you can get one 3) ignition up grade 4) proformace cam shaft 5) make sure it runs at 210 temp or lower but not to low 6) new headers. As for sound the new headers will help alot but i put a cherry bomb glass pack on my xj it's 26 inches by 2 3/4 inches. I cut off my pipe after the cat. and clampped it on then put a tip on it. It sounds awsome im always setting car alarms off aorund town and turning heads. hope this helps you.
