I get asked daily about where to get a MAP sensor and rather than continue to reply individually, I figured I'd put this here for all to see. Here are the known (to me) 2 & 3 bar MAP options:
GM - 3 bar - 12223861 - $102 from GM Parts Direct (LINK).
MSD - 2 bar - 2312 - $72 from Summit (LINK)
MSD - 3 bar - 2313 - $95 from Summit (LINK)
Autometer - 2 bar - 2247 - $90 from Summit (LINK)
Autometer - 3 bar - 2249 - $90 from Summit (LINK)
1A Auto - 3 bar - 1AEMP00001 - $26 from 1A Auto (LINK)
I know there are A LOT more (other GM sources, Accel, eBay, etc...) but these are the ones that I have had experience with. Note - I have not personally tested the Autometer ones, only know that they have worked for others before (local TTA owner and others online). If you get one of these (or any of them for that matter), make sure there is a return policy and a warranty.
