I was doing some reading on fabricating a cold air box for my cone filter to reduce intake temps, and I stumbled across this page

http://autospeed.com.au/cms/title_Building-and-Testing-an-Airbox/A_110281/article.html

This guy has an interesting approach, where he actually put a scoop on the hood to pull cold air in. I've seen a few scoops that I can salvage from cars at the wreckers.

What I was pondering is, will it be any more efficient/beneficial to put in a scoop, instead of pulling air from where the stock air box gets fed from (in the fender)

On the other hand, if the end goal is a FMIC, is there any point in chopping up the hood.

If you're going FMIC, don't bother with chopping up the hood.

Take the cold air from the stock location or the fender well. No sense choppin up the hood.

In the 4th gen celica, you can drop the stock air box and resonator (in the fender well). Route an intake and filter into there, and you have CAI without modifying the hood.



If you're going FMIC, don't bother with chopping up the hood.

While I agree with this, I still think a scoop isn't a bad idea, especially in high-temp areas (such as AZ..)

I think a Small, off center scoop could compliment a car well; if it is truly functional and well done.

I was and am still considering creating a drop vent for my 165. Creating a low pressure zone to draw the hot air out. That's for heat evacuation tho as opposed to air induction. To get cool air in, I have a hose fed from my front bumper, by the tow hook, to where the intake is. Works well.

Maybe another area to consider is pulling the higher pressure air at the base of the windshield.
