Cone filter+ extension kit

I tried putting a heat shielded cone filter with an extension kit to my 98 gp gt. The best way I could do it was by putting the cone filter in the opposite direction, other wise the extensions would be loose. Is there anything wrong with doing this??

I'm confused. You have the filter facing the passenger cabin?

If you have the filter facing the firewall it would do you more harm than good. The air there is really not much and too hot. There is a posting where JoeJoe shows his extention to the fender and mine with a CAI. You should do the CAI or just get rid of the OEM airbox and put the CONE there on the rubber duct, but NO NO puting it facing the firewal

Ok let me explain my setup better. I have the factory rubber tube on with the sensor and then there is a metal heat shielded cone filter attached to the rubber tube at one end and to the extension kit at the other. The only air into the engine is from the extension kit and the lower left side of the car. I'm also going to cover this with a heat shield I got from home depot. As long as the filter works the same from both sides I don't see how it could make a damage.

Oh and by the way I have already removed my airbox.

Ok, now I understand what you have. In that case what you have would look like the setup they use on BMW's where they leave the cone open just with a metal shield facing to the side where the engine is relative to the cone. Check the following http://www.zzperformance.com/zzp/info/intake_designs_airflow.htm and also look into http://www.easyperformance.com and look under Tech Info look for CAI design primer. AS you can see on these sites it is better to have the cone as close as possible to the TB. In your case get rid of the long tube and shield the cone from beneath and to it's left. WOuld be a lot better of you get someone that makes up an acrylic enclosure for your cone or from other non flamable material or get a CAI

This is what it looks like but the cone filter is attached in the opposite direction:

I was told that the extension kit was the best way to avoid waterintake.

Just check the urls that I pasted before. Make sense for the water but the elbow takes aways a lot from the flow, so what you gain in one side you loose it on the other. Chech the URL's that I posted. The shorter and no elbows the better.

Thanx for the websites. I think I'm gonna get rid of the L bent put the cone in the right direction but still use the tube and give it a bigger curve to avoid that elbow effect. Or I might try it without the hose and maybe find a way to make a hole in my headlights and get the ram effect.

You do not have to make a hole in the headlight. Just take away the OEM air inlet on the fender side that was used originally by the OEM airbox. You get more than enough fresh air thru that without braking your headlights

You r right It works. I took the extension kit off shielded the factroy tube and my cone and just point it toward where the OEM inlet was. After driving for a while I put my hand arround the filter and the air was pretty cool. So tell me why would someone use a CAI if the short intake does the same?
