Jordan, what size/thickness foam are you using for this?
I used this 5/8" thick foam: Amazon.com: Uni Filter BF1 12" X 16" X 5/8" 65-PPI Green Fine Foam: Automotive
My post about the install:

Also, my Blackstone oil reports show less-than-average silicon content in the oil so the air filtration is top notch as intended.
Any engineer would have to get excited about that :whoo:
