I'm not trying to undermind your knowlage nz so please don't take offense.....but i dissagree about you statement. From what i have read in various r&T articles and and other publications the "snorkel" was placed where it was for "maximum fresh air flow" without sacraficing structural integrety and minimizing space...It was placed behind the gap between the hood and the bumper for maximum "FLOW" not Sucking power.... ....But the "experts may be wrong"......experts are usually just boneheads behind a desk with pocket protectors and fancy degree's, now i don't know whom to believe....damnit!

IMHO,
The area where the stock sorkel comes into the front bumper is not a high pressure zone compared to the engine bay where the air box is/was.

At least not enough to offer any significant air flow through this snorkel.

Plenty! I just keep real quiet when I don't know

When they say "maximum fresh air flow", they're overstating the case quite a bit. That sort of implies air being forced into a duct, but manufacturers never do that because it increases the chances of dirt and foreign objects being sucked into the engine. They generally position intakes to make the least noise (their #1 priority) and to get to relatively cool air.

When the car's moving, the area in front of the radiator (which is where the snorkel sucks from) is at a slight positive pressure, but it would be very small. It wouldn't be enough to push enough air down the open snorkel to make any difference. With a pod filter in the engine bay, nearly all of the air entering will be what's been through the radiator, not the snorkel. You'd have to go to quite some effort to make a heat shield that totally sealed off the pod filter so it could only be fed by the snorkel, but how much better than stock is that going to be?

Hey Mark, I tried your configuration. It seems to be better than the "Dragon system" I just bought.

A sponge for a filter sucking hot air from the engine bay is better than the "dragon system" or any OBX superdupercoldairmicromacrofilter that you can buy

Seriously though, I have a spare airbox top that I'm going to be doing this to... i'll post my results... I just figure that I'll get similar gains with negligible differences to a pod filter sealed away from the rad.

NZ,

According to your point about the air box being sealed in order to have the snorkel work.. Then wouldn't cutting the holes in the box unseal it?? Do you think the snorkel would still work after this?? Thanks for all your help and knowledge..

Yeah, I was just wondering if ANY cooler air would still be drwan into the engine bay without the box in place.

Less air will be pulled through the snorkel because some air is now coming in the new holes. While this would increase intake air temps, it would also decrease the restriction caused by the top half of the box (including the snorkel).

This is probably a good compromise between an untouched stock airbox and an exposed pod filter. Not as much of an airflow gain, but not as much of a temp increase either. It's still not as good as a properly shielded and ducted pod filter, but it's a lot less work too.
