currently running with the pop charger intake, i have removed the snorkel and the scoop sections on my 97 maxima gxe. i was just wondering if the tubing helps the cone receive cooler air. i removed it because it seemed like the plastic tubing had no more use. i noticed the other night i couldn't chirp onto second gear anymore on my usual testing road. now it only has a scrubbing sound instead of an actual tire squeal. it was very humid, and warmer however.

 

no use, I believe that the cone you will lose low end and gain high end

 

i left the plastic on my car because it brings air right to the cone. thats the way the stock filter gets it's air. i also have an obx filter that has a V-shape filter in the center which also helps ( but this type of filter is very loud at fot.)

 

the air duct brings air to the stock intake because it sucks it through there but since you have a cone, there isnt any force sucking the air throught there and I doubt that the air will have enough force to travel in up and throught the duct

 

but when you start going fast all the air rushing thew the grill ( which is forced air ). this extra air is free, not only do you have the air around the cone but now you have cooler extra air coming threw the plastic.

put your hand out the window when your driving around at 20mph then floor-it. when you hit about 50mph now your hand is being hit with the force of the wind. this extra air will help the filter. race cars have vents in the window for air but they don't work until they start going fast. i drove my car at about 80mph for about an hour when i stopped i quickly opened the hood and the eng. was cool no hot air rising from the motor. so when they say that your filter is sucking up hot air, i think it's only when driving slow but when driving at 50 mph the air is not that hot unless it's really hot like 90.

 

You should have left the intake snorkel in along with the lower section of the airbox if your filter will allow it. Seeing that it is a "hot air" intake, you need has much cooler air blowing in there. I've got a hose attached to to the fender side of the airbox and I've still got my OSCAI tubing attached to the stock intake snorkel. Both these extra air pipes are routed to where I've got my Hella driving lights in the factory holes. I've also built a heat shield to stop radient heat from the motor.

At a stand still, the underhood temps will rise quickly, but once your rolling the temps will fall. After cruising on a sunny 85 degree day for about 30 minutes, with stop and go traffic (0 to 40mph), I pulled over a felt my intake. It was barely warm.

i left everything but the box. my filer is never hot unless i'm in stop and go traffic.

 

without the tubing i can see the ground..i figure with all that open space there will be turbulence in the engine bay anyway..does it really matter that much? does anyone know for sure if it will hurt my car's performance? right now its 50/50.
