quick mods for under $100?

anyone know of some good mods that are pretty cheap? do plugs and plug wires have much difference on the performance? and ground wires? im looking towards engine wise not stuff like weight reduction or rims.

the only thing i can think of that'll cost you less than $100 would be your own custom cold air or short ram intake. you can make it out of aluminum or pvc piping and buy a K&N filter. it won't give you the gains of a commercial one, but it'll do the job.

you can also buy it one on ebay relatively cheap. also, don't be fooled, putting one of the Prelude TypeR emblems sold on ebay will get you no gains! neither will a neon underglow kit :D

Cheap mods... really don't exist.

umm.. low temp thermostat/fan switch, ive seen muffler shops do "straight-pipes" for around 100$

well still about thos spark plugs and plug wires... do they make a diff in performance? some say it increases horsepower?
