With the non-flanged one, you have to buy a coupling, so it might not be worth it to you. By the time you have sold the maf adaptor, you will have to turn around and buy the silicone coupling. Plus you lose the rigidity that the MAF adaptor gives you. Its probably break even, unless you want a bigger filter than 9".
