stock sizes of MAF and TB
 

i have a 2002 z28 and was wondering what the stock sizes of those are? thanks

I read somewhere on here that the maf is around 72mm and I think the TB is 75mm but don't quote me on that! :)

I believe they both are the same, 72mm.

Throttle Body is 75mm.

Moving to Newbie Tech....

their both 75mm on a ls1

75mm on both

Answered my question as well :)

is this the outside diameter?
 

Is this the outside diameter on the TB and MAP?

its then entrance

Not exactly. The entrance, or outside diameter of the TB is 4", then tapers down to 75mm (~3"). The MAF should stay consistent throughout, with little or no change in size.

MAF tapers just a little, the t/b is 75mm at the blade

guess i should have made that clearer, now that i read it...it could have meant anything

its ok jacob, i knew what you meant by it
