How do I know what size MAF and throttle body I have? The truck was bought used and already has some mods, I just don't know what. I can post pics if that would help. Thanks!

 

If it's a 99/00, it could have the stock 80mm or a new 90mm??? If it's a 01-03, it has a 90mm MAF.

Yeah I know, but I don't know how to tell the difference. It is a 99 so it should have came with a 80, but I think it may have been changed. I don't want to order one when it may already have one.

 

ill get the part number off my 01 90 mm when i get home in a little while.

 

Thats awful nice of you latemodel for elpin out like tat sucks

 

I think that the last two numbers on the maf will be 90 on the 90mm sensor, not sure on the rest though.

 

Where are the #'s at? Is the stock bottom pully silver? I have no clue and can't find any pics of a stock pully. What about the top pully? My boost gauge goes into the black, way past the 10 mark. I just ordered a boost gauge from jegs, it should be in in a couple of days so I will know for sure then. Any help is more than appreciated. Also anyone in GA check out http://home.speedfactory.net/ukyo/trackday/track.htm last year I got more runs than I could even use. Lots of fun plenty of nice people.

 

Well no part numbers?

 

Here is what I found on my OEM MAF on my 01L:

1L3F-128579-AB (guessing that's the p/n?)

AFH90-02

IC14

Where did you find the numbers at? I appreciate any of the help anyone provides me!

 

I forgot you last night
1L3F-128579-AB

AFH90-02

1e16


and on the actual round part of the mass air it says
>pbt-gf30<

 

Those numbers were on the 'square' piece that is part of the MAF--where the electrical connector attaches.

Ckeck out any of the Photo gallery sites for pics of stock pulleys or look at the Supporting vendors sites for copies of their pulley install instructions. There shoudl be pictures there to0

 

Stock left 2lb right and the 4lber is kinda busy right now. It is silver.

 

Mine has definatley been changed on the bottome end because it is now hollow like the pic on the right. What #er it is i guess I'll find out when I put the boost gauge on, it should be here tommorrow.
