I know my Stealth, Quickfuel 650 SS with a small 5/16" Isolator and 1" drop base clears.
With out the spacer and drop base it put the air cleaner lid into the hood insulation. I have a nice Mopar logo and fins imprinted into the insulation now..
So you may want a drop base at least.
I bought this to remove the air cleaner stud and wing nut. It works trick!
