Default 1994 Style air box?

If I removed the pipe that goes from the front of the intake box to the back of the headlight, how much extra air flow do you think I would get being that pipe narrows towards the headlight?

its funny that you asked that because I just did that last night. It gives that exhaust a little lower pitch and more growl. It might not be good that it is sucking warm air form the engin bay though? IS this true??

PA owners think alike

PA owners do think alike! Anyways I am trying to think of ways to get more airflow without having to resort to buying a kit just yet.

Yeah, the air would be a little warmer, but not much, I would think. Is the box gutted? That would yield more flow...

I took off that crappy pipe today, went to home depot and bought a rubber 3 inch pipe coupler and put it on it to extend it more towards the front of the car. I can tell already a pretty good power increase since I have done this. She is alot more peppy than usual. I held the old pipe up to the new coupler and theres a little over an inch difference ( compared to the narrow end of the stock pipe, which I think abouts to alot more flow. You can also hear it sucking in air from out side the car with my fans running. It worked out very well. As for gutting it my 94 box has nothing in it so gut.

Day 2 and still have a good power increase. Hoever my gas mileage sucks again. Must be cause the PCM has to learn the changes in air flow. From the amount of gain I recieved I dont think I will be investing in a kit yet.

Most of the times you see a slight increase in gas mileage. But your O2 sensor could be bad even though you just bought it. I would reset the computer and try it again.
