I tried both a 3.5" and 4" coupler. The 3.5" fit on my maf but not my stock tb and the 4" fit my tb but not my maf (half inch of space left). are you guys sure a regular 4" from intake hoses will fit no issues?

I looked for smoother options, but the 93 Firehawk airbox is such a one-off.
A 6x4 rubber coupler seems to work just fine, even if it's ugly. The smooth bellows site
mentioned above has some nice looking options for other setups.
