Originally posted by HoosierContour: 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".
For most cases, this wouldn't be true. Most aftermarket filters will slip right over the inlet to the maf. All you would need is the metal clamp to tighten it on, which usually is on the filter already.
