45mm DCOE or DHLA 44mm x 1/2" thick CNC milled aluminum (6061) mounting flange / spacer. The mounting holes are 6.8mm (correct size for tapping M8x1.25 studs).
If you are making your own intake, this could make it easier for you.
Stud kits can be found here.
I do combine shipping so if you buy multiple items, let me send you a combined total.
If you plan to use as a spacer, you will most likely have to drill the mounting holes out larger to fit over your studs.
Custom work available, just ask.
