Front loader was a good revision, I think.
I'm curious how much flow difference you notice out of the vents. That looks great man.
I was looking at it, after I installed them, and was like DANG they will go either way
Took longer to remove the door surrounds and padding than to install them.

I wonder if you would get more air intake if you pointed the filter up and moved it under a cowl vent? Cleaning it should be easy, since I see the screw to remove the filter. As it is, that probably works well to not only filter the particles out from breathing dirt on off road excursions with the fan or AC on, but also keeps debris out of your AC system. Great idea.

Great to hear that the A/T’s wore so well. I’ve yet to test out how grippy they are, but I will!
It wouldn't matter. Well actually it would. It would get the filter wet when it rained. But before that, it wouldn't make it flow anymore.
I feel like the issue there is possible water infiltration, I chose the back angle based on studying the factory duct. Might still need some tweaking but it was a start. It actually draws quite a bit of air as is. I checked it before replacing the cowl and it's definitely pulling. Since I'm doing a full function test on this one, I checked it after installing the cowl but before running to the local pub for a sammich and a few cold ones in celebration....it was sucking quite a bit of air through the central cowl vent. Remarkable positive air flow with the system running.
With the K&N, filter change period would be longer, individual environmental conditions and usage dependent. @jscherb has been cleaning house recently and is offering up his mold masters for his cool cowl, I considered the possibility of snagging those bits to develop a fiberglass cowl panel replacement with filter access door....
The cowl intake isn't going to be the limiting factor. There is more than enough open surface area there plus there is an opening for water to drain through the cowl to the ground. The flow I was curious about was with the filter in place vs open. I suspect you are going to see a noticable drop in air flow from the vents. I hope not, but I think so with that size filter.
Appreciate you saying so. The glue up could have gone better, my AC kicked on when I was doing the work in the mancave and accelerated the acetone evaporation, reducing working time and increasing glue viscosity. That said, I think she'll break elsewhere before the glue joints give.
The additon of the filter doesn't seem to noticeably affect/reduce air flow inside. I've seen some guys adapt engine air filters to do the job, but the issue there is that those filter elelments are designed to stand up to engine intake suction levels, whereas the blower motor is likely less robust. The element seems well suited for the blower's power.

WOW its looking great,
I wish you were closer. Maybe you should come out next summer and we could do the Rubicon
WOW its looking great,
Man thanks- i’m getting pretty stoked.
I’d love to do that- not dead sure how I’d do the logistics.
I’m also thinking how to take one of mine down to see @Jerry Bransford this fall-
I head to Wyoming week after next for our 30th anniversary.
Work will be saner next year. Like to at least meet up with some of you in Moab or the Western Slope.
Got a little rain last night. I thought I was in Florida for a minute.
Geeeze!

If anyone has any inexpensive but accurate ways of measuring the air flow, I'd be keen to test and see.
Would a Kestrel measure accurately enough? Not exactly inexpensive but not crazy either.
3D print this:

3D print a custom bracket to attach to the passenger grab handle.
Attach a magnet to the shaft and 3D print a bracket for a hall sensor.
Attach the sensor to an Arduino to log the rotational speed while you are driving.

Tape a small cardboard box over the vent, cut a hole in the box and tape a strip of paper at one end above the hole, so that airflow causes the paper to rise.
Point a camera at 90 degrees angle to the paper and record while you are driving.
Open the video on your PC, capture a still at the maximum or average point of the paper rising and measure the angle.
