I am trying to make an intake that is larger than 4", but the only MAF housing I have been able to find it 5'.

LS7 card insert. Use any size pipe you want and tune for it.

I was hoping that someone already made one, instead of me having to have one welded together.

Unless you're planning on north of 1000whp you don't need anything bigger than the Spectre 4 inch tube.

yeah. 4" is as large as they go, and they don't have a screen/air straightener.

I actually have a 5" screened MAF and couplers right now that I am trying to get to fit. I am asking about the 4.5" in case the 5" doesn't work.

In the voice of Crocodile Dundee.......

That's not a MAF


THAT'S a MAF!!!

Better how? Just throwing in the biggest tube as possible isn't automatically better. There are drivability considerations.

I know. If it doesn't work, oh well, I'll go back to 4". Just need to replace the screen, and not mangle it getting it in this time. lol.

Fits under my Raptor hood. Factory Hood would almost definitely crush the filter.

That giant tube and you put that poor little filter on it?! Get something oblong and fill that whole area.

I was trying for two 4s on a 5x4x4 Y, but that would not come close to fitting

Check out AFE and R2C filters. They both offer a huge amount of different sizes and you can even build you own.

I adjusted the new throttle body blade until HP Tuners showed the TPS voltage jumping between .63 and .65. Drove to the gas station and back, and it drives and idles with no issues.
