Ok, I made a low cost CAI here and took a few pictures to show how it was done. Not including the filter, the cost was about $5

PVC is the WORST thing you could have used.....you would have been better off gutting and using the stock airbox

Please let me know why, there are several people around here that do use it. If there is a problem I would like to know.

When heated up PVC (Polyvinyl Chloride) gives off hydrogen chloride gas and when mixed with moisture makes some sort of acid(hydrochloric I think) as well as several other types of gas that can be hazardous to your health. I dont know what it does to a combustion engine or your exhaust system, but it cant be good.

the accordian tube from the stock setup is quite restrictive if i recall correctly

Is there any proof , as some people think it is better.Just curious cause the performance shop I bought my filter from said people are using PVC OR (or the other plastic pipe at hardware stores) and I told him its no good and he said it was not true , it doesnt heat up as much as steal blah blah.Like I said I dont know but would like more proof.I dont use it on my 2000 but I do on my 90 beater
