I scored a pro flow adapter plate, now I need to find the part number for the largest filter I can get to fit into the stock airbox with the adapter. If you also have the pre-filter number that would be great.

Easy...Shoulda just asked....I guess you did

So is the 4710 the longer filter that you said might not fit the stock airbox?

All you need to do is measure the lenght of the air box...the is the only variable you need to verify...My box is gone...the filter is 6.75inch the flange is like3/8, the adapter is aprox the same...

I'd say if you got like 8.25 inch your good...without any cutting...

Well, the airbox is 8.5" long so looks like I can use the longer of the two.
