Nice but you need to cover it up so it sucks outside air through the hole in the fender or some other source.
You do not want to be sucking the hot under the hood air. That's really no better than having your PMD in there
I use the K47 air filter boxes. You could easily fab something as good or better and screw it to the fender so you would suck outside air through the OEM hole
I've got no use for the pre-K47 flat panel air boxes, They are about worthless
I prefer using the old elbow and the PVC. I have some aluminum couplings I am going to cut and weld to replace the PVC elbows. After I get all the things done that I have to do. Someplace I have the appropriate O.D. that the fitting needs to be for proper fitment inside the air filter and turbo elbow.
Could you post the dimension of the part that goes into the filter?
