I worked over the first video with the new run videos, new intake picture, graph, numbers, etc.
Well it had to come out sooner or later, the intake does indeed use the same shape filter as the factory filter, so there are lots of options for filter brands, and they are easy to come by...
Why did I choose to utilize a factory drop in replacement? 1) Obviously cost is a reason. They are readily available, and there are several brands to choose from... 2) The shape was prefect for where the intake mounts to allow the velocity stack / filter clamp piece to clear all the A/C lines, radiator, and radiator hose. I do not think I could have pulled it off so cleanly with a full on square/rectangular filter. 3) Although I'm sure it would rarely happen, another benefit to using the stock shape filter is that in the event of an emergency where the filter is ruined (Rodent eats it, sucks in a small child, etc), a replacement can be found almost anywhere to get you going down the road again. Would it be an optimal filter? Most likely not, but one can be had easily, and get you on your way.
Pictures below show the intake in it's true form (although the MAF is on the wrong side)... No camera tricks to make it look like it doesn't use a factory drop in filter...
If you follow the random crap I post about filters, etc, I think you can see why I am a fan of the drop in filters now. In the right application (this), they flow an incredible amount of air, and there is absolutely nothing wrong with using a drop in filter.
So how many jaws hit the floor after dropping this bomb?
