Phil Hyde Posted August 15, 2021 Share Posted August 15, 2021 What is the consensus on a replacement MAF for a 1991 EA82? Subaru parts seem scarce - only found them on eBay. Is aftermarket over the counter sufficient? Auto zone, NAPA, etc? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 16, 2021 Share Posted August 16, 2021 I would trust used factory over anything from any parts store. MAF sensors are HIGHLY calibrated sensors and in virtually every case I've seen of aftermarket replacement sensors for older vehicles they are scaled incorrectly resulting in poor operation and huge fuel trims. OEM Subaru new or used only in this case. GD 2 Quote Link to comment Share on other sites More sharing options...
DaveT Posted August 17, 2021 Share Posted August 17, 2021 In general, for EA82s, you want to start collecting spare parts whenever you find them. Many are NLA from Subaru or the aftermarket. Quote Link to comment Share on other sites More sharing options...
dameson Posted August 24, 2021 Share Posted August 24, 2021 Using an aftermarket MAF sensor is a hit and miss. Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted August 24, 2021 Share Posted August 24, 2021 This is specifically about EJ MAFs, but the same principles apply to any 'OEM vs. aftermarket' electronic component discussion. Quote Link to comment Share on other sites More sharing options...
