Default Do 90mm Intake/TB need 90mm MAFs???

Got my 90mm FAST in the mail yesterday... Damn

Now i'm thinking that I have to change my entire air inlet plumbing from the airfilter.

Will I need a 90mm MAF too?

No. But, if you have a 78mm I'd get an 85mm MAF.

go SD and ya wont... otherwise you atleast need an 85mm maf otherwise you will not get full advantage of the 90mm....... throttle response will pick up regardless though.

Mind my ignorance-- What's SD stand for?

Yes my previous setup is 78mm TB with LS1 electricals. To use this 90mm, where do I get the hoses and parts? Will a MAFs off of LS2/LS7 cars work?

Thanks,
