FAB-320 vs FAB-360/540

[jerry98b]

Background: I have an O-320 that I am converting to fuel injection to install on my RV-9A.

I have a FAB-320-1 air box kit. Can this kit be used or do I need to purchase a FAB-360/540 kit? What is the difference between these two kits?

Thank you!

The link below will provide guidance.
Most IO-320 vertical induction engines use the FAB 360/540 airbox which requires this filter.
The E-3450 is 2.5" high, 6.25" ID, 7.75" OD. and fits the FAB-360/540. (text is from Vans store).
