Genuine Silver badged Delphi MAF, This is a used unit, i have cleaned and tested. Good for around 11400hz

$90 + Post

is this as seen on stock ls1? or is bigger?

I believe this is as seen on LS2 & possibly L76/L98 but they are 1's that are hard to find & there's a lot of knock off's that don't have the higher Hz scale!

there used on VZ V8's i think, but this was from the US Chev Tahoe use them. I got 2 in from the US to retest after the AU ones were found to be limiting to 11,500hz or around there, seems these do as well, was just a brand new one that went to 14,000hz perhaps a revision in the new ones and they can read higher but seems anything used i have tested or anyone else so far is limited to around 11,500hz, the plastic acdelco ones are heading around the same limitation as well.

so I would need an adapter loom to use this on my ls1 as well?

LS1 has 3pin MAF and 2 pin IAT?

yep

You will need the joiner to 5 pin, same as the ones i have for sale but has different MAF plug, ive just put up a post in enhanced thread about which plugs fit which maf's.

Sorry don't want to confuse things but LS1 maf's actually only have the 3 pin plug with IAT seperate, from what I've worked on anyway!

which is exactly what The1 meant... 3 pin Maf plus separate 2 pin IAT...
