You think you can take some pictures of what you did? Sounds interesting.

The K&N is not an open cone...it's a closed cone (sealed end). I (remember that I) had an S&B Powerstack filter on my Explorer...and those are open cones...notice the open end:

Wouldn't it seem you'd get more air from an Open cone vs. a Closed cone filter?

[HEY CORNY>>>I SEE A RED ONE IN THAT PIC ]
Sorry about that. I did have an S&B Powerstac on my old Thrasher CAI. When I took out the S&B Normal cone and put the powerstack in, I did see alittle change, but not enough to buy another one.

sprayed what with the paint - the K&N shield?

and then you put the reflect-a-cool on the inside of the shield, with the shiny reflective side facing the filter?? the reflective side should be facing the heat source... so it should be stuck on the "outside" of the shield facing the engine, no??

I'm pretty sure it insulates against heat, so inside the K&N box.

- I layered reflect-a-cool on the outside of the K&N Heat shield
- Then I took off the drivers side front tire and weather cover
- I ran a 4 inch (tube) from underneath my fog light where there is a gap to the rectangle hole that is down by the CPU where the K&N is.

Tested it was holding the heat in the enclosure. So I took it off and insulated the inside of the K&N heat shield and I had almost 30 degrees cooler then stock or the intial way I installed the reflect-a-cool.

Maybe you put this around the K&N heat guard box to reflect more heat away
from the intake tube and filter.

Bill, i thought the complete opposite...with the air coming in from the top AND sides it'd be more uniform airflow...instead of crashing into eachother from opposite. Ultimately, the MAF screen does straighten out the air for the sensor...so in the end the turbulance could be a non-factor.

Scarlett, that's interesting...it says to put that stuff facing the heat source...so one would assume it goes on the OUTSIDE of the airbox.

Anyway, i was considering purchasing some rigid insulating foam and installing that...but i haven't done it yet b/c i'm broke and overall lazy LOL.
