the rubber pipe that runs from my air box to my throttle body has bumps in it you could say, its not flat on the inside...ups and downs, for flexibility if I put larger rubber mounts on the air box and a straight piece of pipe inplace of the non-smooth flowing rubber one would that help flow better? anyone ever tried?
Also the airbox'* intake tube went down to like 1 1/2" from 3" so I put a piece of 3 inch pipe off it to behind the headlight, and it seems like it has helped.

Thanks guys

I'm pretty sure people have replaced the "accordian tube" as we call it with smooth walled tubing. I can't find an example right now but someone will chime in i'm sure.

Edit - not sure about on a 1990 though :?

smooth walled tubing....good one...and theres no reason I can't go ahead and do it, just gonna put bigger rubber mounts on the airbox so it can move wih the engine if need be.

why not just get a cold air intake at that point?

isnt the function of the "accordian tube" is supposed to be for silencing, i think, but it probably would increase airflow but for the worka cai might be the better bet. but if you just do the staright pipe, i would suggest using something that doesnt conduct heat very well like metal, and if you do, use some sort of heat wrap around it.

Be very careful in your material selection. What you might think is good may actually be the worst thing you can do.

So guys, I need a piece of metal pipe, should it be painted on the inside/outside with heat paint to prevent rusting? or just leave it as it is? And I will be getting heat reflecting tape.(non-insulative) Home Depot sells this kind of tape or am I mistaken? thanks for the replies guys

Read the link I posted above. HD tape will hurt you, not help you. It reflects from both sides. In other words, it holds heat in, and won't let it out. You need a product designed to prevent heat from getting in, and let out what comes in from the TB.

I did read the link and if you read my post you would realize it says 'heat reflecting' and 'non insulative' maybe this stuff'* not tape then that i need...but no ones said that yet or even what it is so ill consider it heat reflecting non insulative tape until told otherwise.

You didn't read that topic very well.

It'* clearly stated you need a product specifically designed for this purpose. None of the reflective or insulative products at HD or Lowe'* will work right. As a follow-up, we did test my conclusions on another car here with the same results.
