5.0s are steel.. 4.6 are plastic, or was it just 99+ 4.6 that are plastic?

Mine is metal I believe.

Would it really do anything considering the tubing and TB are the same size. Right? TB and tubing is same size as MAF?

the stock maf is 55mm and the tb is 65mm. i wouldnt try to port the stock one. you will throw the ecu off. just get the 73mm from c&l. it will be your cheapest way to go if thats why your thinking of porting

wouldnt try

hes right, the stock MAF are cast aluminum and should not be ported. you will de-calibrate it, just buy one from jdsperformance.com for 119 bucks. i got the 73mm one and its worth every penny.

Looking into the 73 or 76 from C&L.

Should I get the same size tubing that is optional with it? If I do get something like this what kind of difference could I see. Or would I see anything at all?

as i always said dollar for dollar the MAF is the most powerful mod. for 119 bucks you can free up a good 15 HP. not a bad deal i say.
