Q45 mafs
 

I have a 91 240 with a red top sr and i recentally ordered a mafs from a Q45, shortly after i ordered it a guy told me that they dont act right and it messes up on the sr20 does anyone have any experience with the Q45 mafs

never heard of that, of course u need an safc or some other electronics to make it work with your ecu, the q45 maf is kinda over kill unless your pushin like 600+hp

i would suggest selling it and buying a 300zx maf.

wut about a q45 ignitor chip some guy offered to sell me one for like $20 will it work fine with the sr
